Synopsis

#include <setjmp.h>

void siglongjmp(sigjmp_buf env, int val);

Status

Partially implemented

Conformance

IEEE Std 1003.1-2017

Description

The siglongjmp() function shall be equivalent to the longjmp() function, except as follows:

  • References to setjmp() shall be equivalent to sigsetjmp().

  • The siglongjmp() function shall restore the saved signal mask if and only if the env argument was initialized by a call to sigsetjmp() with a non-zero savemask argument.

Return value

After siglongjmp() is completed, program execution shall continue as if the corresponding invocation of sigsetjmp() had just returned the value specified by val. The siglongjmp() function shall not cause sigsetjmp() to return 0; if val is 0, sigsetjmp() shall return the value 1.

Errors

No errors are defined.

Tests

Untested

Known bugs
