Detach a handler function from a pulse code
#include <sys/iofunc.h> #include <sys/dispatch.h> int pulse_detach( dispatch_t * dpp, int code, int flags );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The pulse_detach() function detaches the pulse code, for dispatch handle dpp, that was attached with pulse_attach().
#include <sys/dispatch.h> #include <time.h> #include <stdio.h> #include <stdlib.h> int my_func( … ) { … } int main( int argc, char **argv ) { dispatch_t *dpp; int flag=0, code, mycode; if ( ( dpp = dispatch_create() ) == NULL ) { fprintf( stderr, "%s: Unable to allocate \ dispatch handle.\n",argv[0] ); return EXIT_FAILURE; } … if ( (code = pulse_attach( dpp, flag, mycode, &my_func, NULL)) == -1 ) { fprintf ( stderr, "Failed to attach pulse code %d.\n", \ mycode ); return 1; } … if ( pulse_detach ( dpp, code, flag ) == -1 ) { fprintf ( stderr, "Failed to detach code %d.\n", code ); return 1; } /* else message was detached */ … }
For examples using the dispatch interface, see dispatch_create(), message_attach(), resmgr_attach(), and thread_pool_create().
