SYNOPSIS

#include <stdlib.h>

void abort(void);

DESCRIPTION

abort terminates program execution abnormally. Open files are not closed before termination.

RETURN VALUE

Control is never returned to the caller of abort .

CAUTION

If you call abort without closing files, data in the files may be lost. In addition, an open UNIX style output file will be unchanged if you call abort . See I/O Functions for a definition of a UNIX style file.

IMPLEMENTATION

abort terminates by raising the SIGABRT signal. If a handler is not defined for this signal, SIGABRT causes program termination with a user ABEND code of 1210. See Signal-Handling Functions for more information about the SIGABRT signal.

EXAMPLE

#include <stdlib.h>
#include <string.h>
#include <stdio.h>

main()
{
   char *passwd, reply[40];
   passwd = "SAS";

   puts("Passwd? ");
   gets(reply);

   if (strcmp(passwd,reply)){
     puts("Password incorrect; execution terminating abnormally.");
     fclose(stdout);
     abort();
   }

   puts("Password is correct.");
}
