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);
