       setjmp.h - stack environment declarations

       #include <setjmp.h>

       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    setjmp(jmp_buf);

	      int    sigsetjmp(sigjmp_buf, int);

	      int   _setjmp(jmp_buf);
