setjmp.h - stack environment declarations
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 pro-
totypes shall be provided.
int sigsetjmp(sigjmp_buf, int);
