Allocate a resource-manager context
#include <sys/iofunc.h> #include <sys/dispatch.h> resmgr_context_t* resmgr_context_alloc( dispatch_t * dpp );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The resmgr_context_alloc() function returns a context that's used for blocking and receiving messages.
A pointer to a resmgr_context_t structure, or NULL if an error occurs (errno is set).
#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; } }
For examples using the dispatch interface, see dispatch_create(), message_attach(), resmgr_attach(), and thread_pool_create().
