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.1‐2017, 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.

APPLICATION USAGE
