Example of Posting a Signal Handler

The following example illustrates posting a signal handler for the SIGABRT signal:

#include <stdio.h>
#include <signal.h>
#include "cobsignal.h"
#include "cobmain.h"

int
mysigcatch(int sig)
{
     printf("In new signal handler\n");
     return(0);  /* Do not process any further handlers */
}

void
mysigexit(cobsigtype_t sighand)
{
    printf("Cancelling handler\n");
    cobremovesighandler(sighand);  /* Remove the handler */
}

main(int argc, char *argv[])
{
    cobsigtype_t sighandle;

    cobinit();

    sighandle = cobpostsighandler(SIGABRT, 128, mysigcatch);
    cobfunc("cobolprog", argc, argv); /* call a cobol program
                                    using cobfunc function */
    raise(SIGABRT);                       /* raise the signal */
    mysigexit(sighandle);

    cobexit(0);               /* Cobexit - close down COBOL
                                 run-time environment */
}
