SAS/C Library Reference, Vol. 1

abend -- Abnormally Terminate Execution Using ABEND

SYNOPSIS

 #include <lclib.h>

 void abend(int code);

DESCRIPTION

abend terminates program execution using the ABEND macro. The code argument is used as a user ABEND code. If code is not between 0 and 4095, the actual ABEND code is unpredictable. Open files are not closed, and atexit routines are not called before termination.

The SIGABRT signal is raised before termination occurs. Program execution continues if the signal handler exits using longjmp. If SIGABRT is managed by OpenEdition software rather than by SAS/C software, the program's final termination status is "terminated by SIGABRT." Also, the ABEND code is not directly accessible to a program running under the shell.

RETURN VALUE

Control is never returned to the caller of abend.

CAUTION

If you call abend without closing files, data in the files may be lost. In addition, an open UNIX style output file that requires copying is unchanged if you call abend. (See I/O Functions for more information on UNIX style files.)

EXAMPLE

 #include <lclib.h>
  #include <stdio.h>

  void fatal(int errcode)
  {
        /* Terminate execution after fatal error. */
     fprintf(stderr, "Fatal error %d, terminating.n",
             errcode);
     fclose(stderr); fclose(stdout);
        /* Close standard files before ABEND.     */
     abend(errcode);
  }
