Digital UNIX Diffs - abort(5)			 Digital UNIX Diffs - abort(5)

NAME
       abort, atexit -	Generates a software signal to end the current process

LIBRARY
	Standard C Library (libc.a)

SYNOPSIS
       #include <stdlib.h>

       int abort ( void );

DIFFERENCES
       vms-process(5): OpenVMS Process Model Differences

       The  abort(3)  function	sends a SIGABRT signal to the current process.
       This terminates the process and produces a memory dump, unless the sig‐
       nal is caught and the signal handler does not return.

       vms-vaxc(5): OpenVMS VAX C vs DEC C Differences

       The  functions  registered  by  atexit(2) to be called when the program
       terminates are called by the VAX C RTL when the process terminates  due
       to a SIGABRT signal.  They are not called under these conditions in DEC
       C RTL.

       In the DEC C RTL, the C signal SIGABRT is defined to be	equal  to  the
       SIGIOT signal rather than to SIGILL as in the VAX C RTL.
