Description:

The dispatch_context_free() function frees the given dispatch context.

This function is part of the dispatch layer of a resource manager. For more information, see “Layers in a resource manager” in the Bones of a Resource Manager chapter of Writing a Resource Manager.

Examples:

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

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

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

   … 

   ctp = dispatch_context_alloc( dpp );

   …

   dispatch_context_free ( ctp );   
   return EXIT_SUCCESS;
}
