Hi,
        This is an ancient snippet of code and I can't remember
enough about it to offer any explanation. Maybe you can make
some sense of it. -Dorrie

#include <signal.h>
void mytrap(...);

.
.
.
.

     pfInit();

       /* if someone quits with ctrl c, clean up pf stuff in /usr/tmp */
       /* needs to be after pfInit */
       /* usually ctrl \ on sgi, by default dumps core*/
    signal(SIGQUIT,mytrap);
       /* usually ctrl c on sgi */
    signal(SIGINT,mytrap);

void mytrap(...){

   /* try not to dump pfUtil file in /usr/tmp */
   /* by dropping through SimDone and doing pfExit*/
   /* pfExit needs to be called by parent process */
   /* can't seem to ctrl C gracefully before sim loop */

     
    pfuExitUtil();

    pfuExitInput();

    pfExit();

    exit(0);
    return(0);

   printf("CHECK for core\n");
   exitFlag = 1;
  }

In main loop check exit flag

if exitFlag

    pfuFreeCPUs();
     
    pfuExitUtil();

    pfuExitInput();

    pfExit();

    exit(0);
    return(0);
