<h3>SETJMP(3)               Library functions               SETJMP(3)
</h3>

<h3>NAME
</h3>       setjmp - save stack context for non-local goto

<h3>SYNOPSIS
</h3>       #include &lt;setjmp.h&gt;

       int setjmp(jmp_buf env );

<h3>DESCRIPTION
</h3>       setjmp  and  longjmp(3) are useful for dealing with errors
       and interrupts encountered in a low-level subroutine of  a
       program.   setjmp() saves the stack context/environment in
       env for later use by longjmp().  The stack context will be
       invalidated if the function which called setjmp() returns.

<h3>RETURN VALUE
</h3>       It returns the value 0 if returning directly and  non-zero
       when returning from longjmp() using the saved context.

<h3>CONFORMING TO
</h3>       POSIX

<h3>NOTES
</h3>       POSIX does not specify if the signal context will be saved
       or  not.   If  you  want  to  save   signal   masks,   use
       sigsetjmp(3).   setjmp() makes programs hard to understand
       and maintain.  If possible an alternative should be  used.
