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 IEEE Std 1003.1-2001,
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 siglongjmp(sigjmp_buf, int);
void _longjmp(jmp_buf, int);
The following may be declared as a function, or defined as a macro, or
both. Function prototypes shall be provided.
int setjmp(jmp_buf);
int sigsetjmp(sigjmp_buf, int);
int _setjmp(jmp_buf);
The following sections are informative.
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
