setjmp.h — stack environment declarations

#include <setjmp.h>

[CX] 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 (“POSIX.1”), xsh_chap02_02(3)) to enable the visibility of these symbols in this header.

The <setjmp.h> header shall define the array types and [CX] .

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]
void   siglongjmp(sigjmp_buf, int);

[XSI]
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);
[CX]
int    sigsetjmp(sigjmp_buf, int);

[XSI]
int   _setjmp(jmp_buf);
