PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       setjmp.h -- stack environment declarations
SYNOPSIS
       #include <setjmp.h>
DESCRIPTION
       Some of the functionality described on this reference page extends  the
       ISO C  standard. Applications shall define the appropriate feature test
       macro (see the System Interfaces volume of POSIX.1-2008,  Section  2.2,
       The  Compilation Environment) to enable the visibility of these symbols
       in this header.
       The  <setjmp.h>  header  shall  define  the  array  types  jmp_buf  and
       sigjmp_buf.
       The following shall be declared as functions and may also be defined as
       macros. Function prototypes shall be provided.
           void   _longjmp(jmp_buf, int);
           void   longjmp(jmp_buf, int);
           void   siglongjmp(sigjmp_buf, int);
       The following may be declared as functions, or defined  as  macros,  or
       both. If functions are declared, function prototypes shall be provided.
           int    _setjmp(jmp_buf);
           int    setjmp(jmp_buf);
           int    sigsetjmp(sigjmp_buf, int);
       The following sections are informative.
