tpfree(3c)
Name
tpfree() - routine for freeing a typed buffer
Synopsis
#include <atmi.h>
void tpfree(char *ptr)
Description
The argument to tpfree() is a pointer to a buffer previously obtained by either tpalloc() or tprealloc(). If ptr is NULL, no action occurs. Undefined results will occur if ptr does not point to a typed buffer (or if it points to space previously freed with tpfree()). Inside service routines, tpfree() returns and does not free the buffer if ptr points to the buffer passed into a service routine.
Some buffer types require state information or associated data to be removed as part of freeing a buffer. tpfree() removes any of these associations (in a communication manager-specific manner) before a buffer is freed.
Once tpfree() returns, ptr should not be passed as an argument to any BEA Tuxedo system routine or used in any other manner.
A thread in a multithreaded application may issue a call to tpfree() while running in any context state, including TPINVALIDCONTEXT.
When freeing an FML32 buffer using tpfree(), the routine recursively frees all embedded buffers to prevent memory leaks. In order to preserve the embedded buffers, you should assign the associated pointer to NULL before issuing the tpfree() command. As stated above, if ptr is NULL, no action occurs.
Return Values
tpfree() does not return any value to its caller. Thus, it is declared as a void.
Usage
This function should not be used in concert with malloc(), realloc(), or free() in the C library (for example, a buffer allocated with tpalloc() should not be freed with free()).
