setjmp.h - Man Page

stack environment declarations


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.


#include <setjmp.h>


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.
