Open System Services Library Calls Reference Manual (G06.27+, H06.04+)

siglongjmp(3) OSS Library Calls Reference Manual
ERRORS
The siglongjmp() function never sets the value of errno. Instead, if the call is unsuccessful, an
undefined signal that cannot be caught, blocked, or ignored is delivered to the calling process.
If the env parameter was saved using the setjmp( ) function instead of the sigsetjmp() function, a
SIGABRT signal is delivered to terminate the process.
RELATED INFORMATION
Functions: setjmp(3), sigaction(2), sigprocmask(2), sigsetjmp(3), sigsuspend(2).
STANDARDS CONFORMANCE
The POSIX standards leave some features to the implementing vendor to define. The following
features are affected in the HP implementation:
• The siglongjmp() function acts as described even if the function is called from within a
nested signal-catching function.
