resmgr_context_free()

Free a resource-manager context

Synopsis:

#include <sys/iofunc.h>
#include <sys/dispatch.h>

void resmgr_context_free( resmgr_context_t * ctp );

Arguments:

ctp

A pointer to the resmgr_context_t structure that you want to free.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The resmgr_context_free() function frees a context allocated by resmgr_context_alloc().

---

This function is a special case of dispatch_context_free(). You should use it only when writing a simple resource manager.

---

Examples:

#include <sys/dispatch.h>
#include <stdio.h>
#include <stdlib.h>

int main( int argc, char **argv ) {
   dispatch_t          *dpp;
   resmgr_context_t    *ctp;

   if ( (dpp = dispatch_create()) == NULL ) {
      fprintf( stderr, "%s: Unable to allocate \
               dispatch handle.\n",argv[0] );
      return EXIT_FAILURE;
   }

   …

   if ( ( ctp = resmgr_context_alloc ( dpp )) == NULL ) {
      fprintf( stderr, "Context wasn't allocated.\n" );
      return EXIT_FAILURE;
   }

   …

   resmgr_context_free ( ctp );
}

For examples using the dispatch interface, see dispatch_create(), message_attach(), resmgr_attach(), and thread_pool_create().
