NAME

13       setjmp.h — stack environment declarations
14

SYNOPSIS

16       #include <setjmp.h>
17

DESCRIPTION

19       Some of the functionality described on this reference page extends  the
20       ISO C  standard. Applications shall define the appropriate feature test
21       macro (see the System Interfaces volume of POSIX.1‐2008,  Section  2.2,
22       The  Compilation Environment) to enable the visibility of these symbols
23       in this header.
24
25       The  <setjmp.h>  header  shall  define  the  array  types  jmp_buf  and
26       sigjmp_buf.
27
28       The following shall be declared as functions and may also be defined as
29       macros. Function prototypes shall be provided.
30
31           void   _longjmp(jmp_buf, int);
32           void   longjmp(jmp_buf, int);
33           void   siglongjmp(sigjmp_buf, int);
34
35       The following may be declared as functions, or defined  as  macros,  or
36       both. If functions are declared, function prototypes shall be provided.
37
38           int    _setjmp(jmp_buf);
39           int    setjmp(jmp_buf);
40           int    sigsetjmp(sigjmp_buf, int);
