NAME

setjmp.h - stack environment declarations

SYNOPSIS

#include <setjmp.h>

DESCRIPTION

[CX] [Option Start] 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. [Option End]

The <setjmp.h> header shall define the array types jmp_buf and [CX] [Option Start] sigjmp_buf. [Option End]

The following shall be declared as functions and may also be defined as macros. Function prototypes shall be provided.

void   longjmp(jmp_buf, int);
[CX][Option Start]
void   siglongjmp(sigjmp_buf, int);
[Option End]
[XSI][Option Start]
void  _longjmp(jmp_buf, int);
[Option End]

The following may be declared as a function, or defined as a macro, or both. Function prototypes shall be provided.

int    setjmp(jmp_buf);
[CX][Option Start]
int    sigsetjmp(sigjmp_buf, int);
[Option End]
[XSI][Option Start]
int   _setjmp(jmp_buf);
[Option End]
