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, 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 [CX]
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); [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);
![]()
