Typedef Documentation

typedef char* _QName

A built-in string type containing normalized QName contents.

typedef char* _XML

A built-in string type containing literal XML content in UTF-8 format.

Function Documentation

void soap_clr_imode ( struct soap soap,
soap_mode  input_mode 
)

Clear input soap_mode flags of the given soap context.

Parameters
soapsoap context
input_modeinput soap_mode flags
void soap_clr_mode ( struct soap soap,
soap_mode  input_and_output_mode 
)

Clear input and output soap_mode flags of the given soap context.

Parameters
soapsoap context
input_and_output_modeinput and output soap_mode flags
void soap_clr_omode ( struct soap soap,
soap_mode  output_mode 
)

Clear output soap_mode flags of the given soap context.

Parameters
soapsoap context
output_modeoutput soap_mode flags
struct soap* soap_copy ( struct soap soap)

Allocate and initialize a new soap context as a copy of the given soap context.

This function allocates a new context and copies the state of the specified context except for the heap-allocated data managed by the specified context. After the copy the contexts do not share any data and can therefore be used by separate threads without requiring synchronization or mutex locking.

Note
C++ proxy and service classes generated by soapcpp2 -j option -j or option -i have an internal soap context that is either a base class (option -i) or a member variable pointing to a soap context (option -j). For convenience, use the copy member function instead of soap_copy and delete the copied instance with delete. For example:
#include "soapexampleService.h" // generated by soapcpp2 option -j
int main()
{
exampleService service(SOAP_XML_INDENT);
service.soap->bind_flags = SO_REUSEADDR; // immediate port reuse
service.soap->accept_timeout = 3600; // let soap_accept time out after 1 hour
... // further initialize service.soap
if (soap_valid_socket(service.bind(NULL, PORTNUM, BACKLOG)))
{
while (1)
{
if (soap_valid_socket(service.accept()))
{
exampleService *tservice = service.copy();
if (!tservice)
soap_closesock(service.soap);
else
while (THREAD_CREATE(&tid, (void*(*)(void*))&process_request, (void*)tservice))
sleep(1); // failed, try again
}
else if (service.soap->errnum) // accept failed, try again after 1 second
{
service.soap_print_fault(stderr);
sleep(1);
}
else // accept timed out, quit looping
{
break;
}
service.destroy();
}
}
}
void *process_request(exampleService *service)
{
service.serve();
service.destroy();
delete service;
return NULL;
}
Example:
#include "soapH.h"
#include "plugin/threads.h"
int main()
{
soap->bind_flags = SO_REUSEADDR; // immediate port reuse
soap->accept_timeout = 3600; // exit loop when no request arrives in one hour
soap->send_timeout = soap_recv_timeout = 5; // 5 seconds max socket stall time (unlimited by default)
soap->transfer_timeout = 30; // 30 seconds max message transfer time (unlimited by default)
soap->recv_maxlength = 1048576; // limit messages received to 1MB (2GB by default)
if (soap_valid_socket(soap_bind(soap, NULL, PORTNUM, BACKLOG)))
{
while (1)
{
{
struct soap *tsoap = soap_copy(soap);
if (!tsoap)
else
while (THREAD_CREATE(&tid, (void*(*)(void*))&process_request, (void*)tsoap))
sleep(1); // failed, try again
}
else // accept failed, try again after 1 second
{
soap_print_fault(soap, stderr);
sleep(1);
}
else // accept timed out, quit looping
{
break;

Returns
pointer to allocated and initialized soap context or NULL when out of heap memory
Parameters
soapsoap context to copy
void soap_copy_context ( struct soap soap_destination,
struct soap soap_source 
)

Copy a given soap context to an uninitialized destination soap context.

This function copies the state of the specified context to another uninitialized context (i.e. overriding it). If the destination context is initialized or active then call soap_done first to clean it up before overriding it. The entire state is copied except for the heap-allocated data managed by the specified context. After the copy the contexts do not share any data and can therefore be used by separate threads without requiring synchronization or mutex locking.

Example:
#include "soapH.h"
struct soap *soap = soap_new();
... // send and receive messages etc.
struct soap temp;
soap_copy_context(&temp, soap);
...
See also
soap_copy, soap_copy_stream, soap_free_stream, soap_delegate_deletion, soap_destroy, soap_end, soap_free.
Parameters
soap_destinationdestination soap context to initialize
soap_sourcesource soap context to copy
void soap_copy_stream ( struct soap soap_destination,
struct soap soap_source 
)

Copy the input/output stream state of the given soap context to another context.

This function copies the input/output state of the specified source context to the specified destination context. Both contexts will share the same input/output streams , i.e. soap::is, soap::os, soap::socket, soap::recvfd and soap::sendfd are shared and the current message buffer soap::buf content is copied. The destination context is set to the source context soap_mode flags and timeouts. To move the input/output state of one context to another, use this function and then call soap_free_stream on the source context to clear its input/output state.

Example:
#include "soapH.h"
struct soap *soap = soap_new();
struct soap *temp = soap_new();
... // send and receive messages etc.
// move the input/output state to another context
soap_copy_stream(temp, soap);
soap_closesock(soap); // has no effect
... // send and receive messages etc.
soap_closesock(temp); // closes socket, if open
See also
soap_free_stream.
Parameters
soap_destinationdestination soap context
soap_sourcesource soap context
void soap_dealloc ( struct soap soap,
void *  ptr 
)

Explicitly dealllocates a block of managed memory that is managed by the specified soap context and release the free memory back to the heap.

This function deallocates a managed block of memory from the managing soap context and releases the free memory back to the heap. This frees data allocated with soap_malloc and C++ objects allocated and instantiated with the soap_new_T functions. Normally this function should not be used to individually deallocate managed objects and data but rather soap_destroy and soap_end should be used to deallocate all objects and data managed by the context, which is much more efficient.

Parameters
soapsoap context
ptrpointer to the block of managed heap memory to deallocate
void soap_delegate_deletion ( struct soap soap,
struct soap soap_to 
)

Delegate the deletion of all managed objects and data from the specified soap context to another soap context.

This function moves all dynamically-allocated data managed by the specified soap context to the target context soap_to for deletion by the target context using soap_destroy and soap_end.

Example:
#include "soapH.h"
struct soap *soap = soap_new();
struct soap *temp = soap_new(); // temp context to manage data
if (soap_call_ns__webmethod(soap, endpoint, NULL, ...))
{
soap_print_fault(soap, stderr);
}
else
{
// success, response contains deserialized data
soap_delegate_deletion(soap, temp); // deserialized data is managed by temp context
}
soap_destroy(soap); // clean up 'soap' context
soap_end(soap); // clean up 'soap' context
... // use deserialized data managed by 'temp' context, reuse 'soap' context as needed
soap_destroy(temp); // clean up 'temp' context, deletes deserialized data
soap_end(temp); // clean up 'temp' context, deletes deserialized data
soap_free(temp);
soap_free(soap);
See also
soap_copy, soap_copy_context, soap_destroy, soap_end.
Parameters
soapsource soap context
soap_totarget soap context
void soap_destroy ( struct soap soap)

Delete all dynamically-allocated C++ objects managed by the specified soap context.

This function deletes all dynamically-allocated C++ objects managed by the specified soap context, i.e. data allocated with soap_new_T calls. This call should be followed by soap_end to delete all other dynamically-allocated data managed by the soap context. Or just invoke soap::destroy to delete objects and data and release the freed memory back to the heap.

Note
C++ proxy and service classes generated by soapcpp2 -j option -j or option -i have an internal soap context that is either a base class (option -i) or a member variable pointing to a soap context (option -j). For convenience, use the destroy member function instead of soap_destroy and soap_end. For example:
#include "soapexampleProxy.h"
exampleProxy proxy(SOAP_XML_INDENT);
... // use proxy or proxy.soap (option -j)
proxy.destroy(); // delete managed C++ objects and memory
#include "soapexampleService.h"
exampleService service(SOAP_XML_INDENT);
... // use service or service.soap (option -j)
service.destroy(); // delete managed C++ objects and memory
Example:
#include "soapH.h"
struct soap *soap = soap_new();
... // send and receive messages etc.
soap_destroy(soap); // delete managed C++ objects
soap_end(soap); // delete managed memory
soap_free(soap); // free the context
See also
soap_malloc, soap_end, soap::destroy.
Parameters
soapsoap context
void soap_done ( struct soap soap)

Finalize the given soap context, i.e. when the soap context is stack allocated, automatically invoked in C++ by the soap destructor on the soap context to delete.

This function finalizes the specified context. This function does not free memory managed by the context. To free memory managed by the context use soap_destroy and soap_end, or soap::destroy to call both.

Example:
#include "soapH.h"
struct soap soap;
soap_init(&soap);
... // send and receive messages etc.
soap_destroy(&soap);
soap_end(&soap);
soap_done(&soap);
See also
soap_free, soap_destroy, soap_end, soap::destroy.
Parameters
soapsoap context to finalize
void soap_end ( struct soap soap)

Delete all data from heap memory managed by the specified soap context and release the freed memory back to the heap.

This function deletes all dynamically-allocated data managed by the specified soap context, i.e. data allocated with soap_malloc. This call suffices to delete all managed data from C applications and release the freed memory back to the heap. C++ applications however should call soap_destroy first before soap_end or just invoke soap::destroy (or C++ proxy and service class member function destroy) to delete objects and data and release the freed memory back to the heap.

Note
C++ proxy and service classes generated by soapcpp2 -j option -j or option -i have an internal soap context that is either a base class (option -i) or a member variable pointing to a soap context (option -j). For convenience, use the destroy member function instead of soap_destroy and soap_end. For example:
#include "soapexampleProxy.h"
exampleProxy proxy(SOAP_XML_INDENT);
... // use proxy or proxy.soap (option -j)
proxy.destroy(); // delete managed C++ objects and memory
#include "soapexampleService.h"
exampleService service(SOAP_XML_INDENT);
... // use service or service.soap (option -j)
service.destroy(); // delete managed C++ objects and memory
Example:
#include "soapH.h"
struct soap *soap = soap_new();
... // send and receive messages etc.
soap_destroy(soap); // delete managed C++ objects
soap_end(soap); // delete managed memory
soap_free(soap); // free the context
See also
soap_malloc, soap_destroy, soap::destroy.
Parameters
soapsoap context
void soap_free ( struct soap soap)

Finalize and free the given soap context from unmanaged heap memory.

This function finalizes and frees the specified context. The finalization is done with soap_done before releasing its memory. This function does not free memory managed by the context. To free memory managed by the context use soap_destroy and soap_end, or soap::destroy to call both.

Note
C++ proxy and service classes generated by soapcpp2 -j option -j or option -i have an internal soap context that is either a base class (option -i) or a member variable pointing to a soap context (option -j). The C++ proxy and service classes allocate and deallocate this context, which means that soap_new and soap_free are not required. For example:
#include "soapexampleProxy.h"
exampleProxy proxy(SOAP_XML_INDENT);
... // use proxy or proxy.soap (option -j)
proxy.destroy(); // delete managed C++ objects and memory
#include "soapexampleService.h"
exampleService service(SOAP_XML_INDENT);
... // use service or service.soap (option -j)
service.destroy(); // delete managed C++ objects and memory
Example:
#include "soapH.h"
struct soap *soap = soap_new();
... // send and receive messages etc.
soap_end(soap);
soap_free(soap);
See also
soap_new, soap_new1, soap_new2, soap_done, soap_destroy, soap_end, soap::destroy.
Parameters
soapsoap context to free
void soap_free_stream ( struct soap soap)

Free the input/output stream state of the given soap context.

See also
soap_copy_stream.
Parameters
soapsoap context
void soap_free_temp ( struct soap soap)

Delete temporary data.

This function deallocates temporary data such as buffers and hash tables but leaves deserialized managed data intact.

Parameters
soapsoap context
void soap_init ( struct soap soap)

Initialize a stack-allocated soap context.

This function initializes a context.

Examples:
#include "soapH.h"
struct soap soap;
soap_init(&soap);
... // send and receive messages etc.
soap_destroy(&soap); // delete managed C++ objects
soap_end(s&oap); // delete managed memory
soap_done(&soap); // finalize the context

The context can be re-initialized for reuse after soap_done by calling soap_init.

Note
Initialization should be done at most once before calling soap_done. To change the input/output mode flags, use soap_set_mode and soap_clr_mode.
See also
soap_init1, soap_new, soap_copy, soap_destroy, soap_end, soap_done.
Parameters
soapsoap context to initialize
void soap_init1 ( struct soap soap,
soap_mode  input_and_output_mode 
)

Initialize a stack-allocated soap context with input and output soap_mode flags.

This function initializes a context with the specified input and output soap_mode flags.

Examples:
#include "soapH.h"
struct soap soap;
... // send and receive messages etc.
soap_destroy(&soap); // delete managed C++ objects
soap_end(s&oap); // delete managed memory
soap_done(&soap); // finalize the context

The context can be re-initialized for reuse after soap_done by calling soap_init.

Note
Initialization should be done at most once before calling soap_done. To change the input/output mode flags, use soap_set_mode and soap_clr_mode.
See also
soap_init, soap_new, soap_copy, soap_destroy, soap_end, soap_done.
Parameters
soapsoap context to initialize
input_and_output_modeinput and output soap_mode flags
void soap_init2 ( struct soap soap,
soap_mode  input_mode,
soap_mode  output_mode 
)

Initialize a stack-allocated soap context with input and output soap_mode flags.

This function initializes a context with the specified input and output soap_mode flags.

Note
Initialization should be done at most once before calling soap_done. To change the input/output mode flags, use soap_set_mode and soap_clr_mode.
See also
soap_init, soap_new, soap_copy, soap_destroy, soap_end, soap_done.
Parameters
soapsoap context to initialize
input_modeinput soap_mode flags
output_modeoutput soap_mode flags
void* soap_malloc ( struct soap soap,
size_t  len 
)

Allocate a block of heap memory managed by the specified soap context.

This function allocates a block of memory from the heap managed by the specified soap context. All such blocks allocated are deleted with a single call to soap_end. Returns a pointer to the allocated block of memory or NULL when out of memory without setting soap::error.

Note
The soapcpp2 tool generates soap_new_T functions for all serialiable types T. The soap_new_T functions allocate and default initializes the type T or an array of items of type T. Recommended is to use these more powerful soap_new_T functions instead of soap_malloc. For example:
#include "soapH.h"
struct soap *soap = soap_new();
struct ns__someElement *data = soap_new_ns__someElement(soap); // allocate managed object
struct ns__someElement *array = soap_new_ns__someElement(soap, 100); // allocate array of 100 managed objects
... // send and receive messages etc.
soap_destroy(soap); // deletes data, array, and other managed C++ objects
soap_end(soap); // delete managed memory
soap_free(soap); // free the context
The soapcpp2 tool also generates soap_default_T functions to default initialize the type T. For example:
#include "soapH.h"
struct soap *soap = soap_new();
struct ns__someElement data;
soap_default_ns__someElement(soap, &data); // default initializes all public members
...
but objects of classes should use their soap_default method instead of the soap_default_T function.
Example:
#include "soapH.h"
struct soap *soap = soap_new();
char *s = (char*)soap_malloc(soap, 80); // allocate 80 bytes of memory managed by the context
strcpy(s, "Hello"); // copy a string into it
... // send and receive messages etc.
soap_destroy(soap); // delete managed C++ objects
soap_end(soap); // delete managed memory
soap_free(soap); // free the context
See also
soap_strdup, soap_wstrdup, soap_unlink, soap_delegate_deletion, soap_destroy, soap_end, and the C and C++ XML data bindings documentation.
Returns
pointer to the allocated block of memory or NULL on failure to allocate (out of memory)
Parameters
soapsoap context
lenlength of the block to allocate in number of bytes
struct soap* soap_new ( )

Allocate and initialize a new soap context.

This function allocates and initializes a new context.

There is no need to call soap_init to initialize the context allocated with soap_new, since soap_new initializes the allocated context. To change the input/output mode flags, use soap_set_mode and soap_clr_mode.

Note
C++ proxy and service classes generated by soapcpp2 -j option -j or option -i have an internal soap context that is either a base class (option -i) or a member variable pointing to a soap context (option -j). The C++ proxy and service classes allocate and deallocate this context, which means that soap_new and soap_free are not required. For example:
#include "soapexampleProxy.h"
exampleProxy proxy(SOAP_XML_INDENT);
... // use proxy or proxy.soap (option -j)
proxy.destroy(); // delete managed C++ objects and memory
#include "soapexampleService.h"
exampleService service(SOAP_XML_INDENT);
... // use service or service.soap (option -j)
service.destroy(); // delete managed C++ objects and memory
Example:
#include "soapH.h"
struct soap *soap = soap_new();
... // send and receive messages etc.
soap_destroy(soap); // delete managed C++ objects
soap_end(soap); // delete managed memory
soap_free(soap); // free the context
See also
soap_new1, soap_new2, soap_copy, soap_destroy, soap_end, soap_free.
Returns
pointer to allocated and initialized soap context or NULL when out of heap memory
struct soap* soap_new1 ( soap_mode  input_and_output_mode)

Allocate and initialize a new soap context with input and output soap_mode flags.

This function allocates and initializes a new context with the specified input and output soap_mode flags.

Example:
#include "soapH.h"
struct soap *soap = soap_new1(SOAP_XML_INDENT);
... // send and receive messages etc.
soap_destroy(soap); // delete managed C++ objects
soap_end(soap); // delete managed memory
soap_free(soap); // free the context
Note
There is no need to call soap_init to initialize the context allocated with soap_new1. To change the input/output mode flags, use soap_set_mode and soap_clr_mode.
See also
soap_new, soap_new2, soap_copy, soap_destroy, soap_end, soap_free.
Returns
pointer to allocated and initialized soap context or NULL when out of heap memory
Parameters
input_and_output_modeinput and output soap_mode flags
struct soap* soap_new2 ( soap_mode  input_mode,
soap_mode  output_mode 
)

Allocate and initialize a new soap context with separate input and output soap_mode flags.

This function allocates and initializes a new context with the specified input and output soap_mode flags. The separation of input and output mode flags is only useful for the SOAP_XML_TREE flag that affects both input and output behaviors.

Note
There is no need to call soap_init to initialize the context allocated with soap_new2.
See also
soap_new, soap_new1, soap_copy, soap_destroy, soap_end, soap_free.
Returns
pointer to allocated and initialized soap context or NULL when out of heap memory
Parameters
input_modeinput soap_mode flags
output_modeoutput soap_mode flags
void soap_set_imode ( struct soap soap,
soap_mode  input_mode 
)

Set input soap_mode flags of the given soap context.

Parameters
soapsoap context
input_modeinput soap_mode flags
void soap_set_mode ( struct soap soap,
soap_mode  input_and_output_mode 
)

Set input and output soap_mode flags of the given soap context.

Parameters
soapsoap context
input_and_output_modeinput and output soap_mode flags
void soap_set_omode ( struct soap soap,

output_modeoutput soap_mode flags
void soap_set_version ( struct soap soap,
short  version 
)

Set SOAP version (0 = no SOAP, 1 = SOAP 1.1, 2 = SOAP 1.2)

This function sets (or overrides) the SOAP version to use when sending a message. This function can be used prior to a client-side call to select the SOAP version to use for the request message (assuming the generated code does not fix the version already) or in a service operation to select the SOAP version of the response message. The response message of a service operation normally uses the same SOAP version of the SOAP request message received.

Parameters
soapsoap contexr
versionSOAP version (0 = REST (no SOAP), 1 = SOAP 1.1, 2 = SOAP 1.2)
char* soap_strdup ( struct soap soap,
const char *  string 
)

Copy a string to managed memory.

This function copies the specified wide string to memory managed by the specified context. Returns a copy of the string or NULL when the specified string is NULL or when the function failed to allocate memory.

Example:
#include "soapH.h"
struct soap *soap = soap_new();
// allocate and assign a string in memory managed by the context
char *s = soap_strdup(soap, "Hello");
... // send and receive messages etc.
soap_destroy(soap); // delete managed C++ objects
soap_end(soap); // delete managed memory
soap_free(soap); // free the context
See also
soap_malloc, soap_wstrdup, soap_unlink, soap_delegate_deletion, soap_destroy, soap_end.
Returns
copy of string or NULL when the specified string is NULL or on failure to allocate (out of memory)
Parameters
soapsoap context
stringstring to copy to managed memory
int soap_unlink ( struct soap soap,
const void *  ptr 
)

Unlink a block of heap memory managed by the specified soap context, to release the memory explicitly later.

This function removes a managed block of memory from the managing soap context. This memory is not released but rather should be released explicitly later by the application logic using free or delete. Returns SOAP_OK when successful or SOAP_ERR when the block is not managed by the specified context.

Returns
SOAP_OK when successful or SOAP_ERR when the block is not managed by the specified context
Parameters
soapsoap context
ptrpointer to the block of managed heap memory to unlink
wchar_t* soap_wstrdup ( struct soap soap,
const wchar_t *  string 
)

Copy a wide string to managed memory.

This function copies the specified wide string to managed memory. Returns a copy of the wide string or NULL when the specified wide string is NULL or when the function failed to allocate memory.

Example:
#include "soapH.h"
struct soap *soap = soap_new();
