NAME
+
       setjmp - save stack context for non-local goto
+
+
SYNOPSIS
+
       #include <setjmp.h>
+
+       int setjmp(jmp_buf env );
+
+
DESCRIPTION
+
       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.
+
+
RETURN VALUE
+
       It returns the value 0 if returning directly and  non-zero
+       when returning from longjmp() using the saved context.
+
+
CONFORMING TO
+
       POSIX
+
+
NOTES
+
       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.
