SYNOPSIS

DESCRIPTION

12       Some  of the functionality described on this reference page extends the
13       ISO C standard. Applications shall define the appropriate feature  test
14       macro  (see  the System Interfaces volume of IEEE Std 1003.1-2001, Sec‐
15       tion 2.2, The Compilation Environment)  to  enable  the  visibility  of
16       these symbols in this header.
17
18       The  <setjmp.h>  header  shall  define  the  array  types  jmp_buf  and
19       sigjmp_buf.
20
21       The following shall be declared as functions and may also be defined as
22       macros. Function prototypes shall be provided.
23
24
25              void   longjmp(jmp_buf, int);
26
27              void   siglongjmp(sigjmp_buf, int);
28
29
30              void  _longjmp(jmp_buf, int);
31
32
33       The  following may be declared as a function, or defined as a macro, or
34       both. Function prototypes shall be provided.
35
36
37              int    setjmp(jmp_buf);
38
39              int    sigsetjmp(sigjmp_buf, int);

41
42              int   _setjmp(jmp_buf);
