LONGJMP(3)              Library functions              LONGJMP(3)
+

+
+
NAME
+
       longjmp - non-local jump to a saved stack context
+
+
SYNOPSIS
+
       #include <setjmp.h>
+
+       void longjmp(jmp_buf env, int val);
+
+
DESCRIPTION
+
       longjmp() and setjmp(3) are useful for dealing with errors
+       and interrupts encountered in a low-level subroutine of  a
+       program.   longjmp() restores the environment saved by the
+       last call of setjmp() with the corresponding env argument.
+       After  longjmp() is completed, program execution continues
+       as if the corresponding call of setjmp() had just returned
+       the  value  val.  longjmp() cannot cause 0 to be returned.
+       If longjmp is invoked with a second argument of 0, 1  will
+       be returned instead.
+
+
RETURN VALUE
+
       This function never returns.
+
+
CONFORMING TO
+
       POSIX
+
+
NOTES
+
       POSIX  does  not  specify  if  the  signal context will be
+       restored or not.  If  you  want  to  save  restore  signal
+       masks,  use siglongjmp(3) longjmp() makes programs hard to
+       understand  and  maintain.   If  possible  an  alternative
+       should be used.
