Summary

The SIGLONGJMP_ procedure performs a nonlocal goto. It restores the state of the

calling process using context saved in a jump buffer by the SIGSETJMP_ procedure.

Control returns to the location of the corresponding SIGSETJMP_ procedure call. The

signal mask is also restored if it was saved; all other signal-handling specifications

remain unchanged.

Parameters

env input

INT .EXT:ref:(SIGJMP_BUF_TEMPLATE)

indicates the address of a previously allocated and initialized jump buffer

containing the process context to be restored by this procedure.

value input

INT(32):value

Note. This procedure can be called only from native processes.

#include <setjmp.h>

void siglongjmp ( sigjmp_buf env

,int value );

?SOURCE $SYSTEM.SYSTEM.HSETJMP

SIGLONGJMP_ ( env ! i

,value ); ! i
