abort -- Abnormally Terminate Execution

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.");
  }
