pulse_detach()

Detach a pulse code

Synopsis:

#include <sys/dispatch.h>

int pulse_detach( dispatch_t * dpp,
                  int code,
                  int flags );

Library:

libc

Description:

The pulse_detach() function detaches the pulse code, for dispatch handle dpp, that was attached with pulse_attach(). The flags argument is reserved.

Returns:

0: Success.
-1: The pulse code doesn't match any attached pulse code.

Examples:

#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 */
			
   ...
}
