pub unsafe fn register_rt_signal_handler(
num: c_int,
handler: extern "C" fn(_: c_int)
) -> Result<()>
Expand description
Registers handler
as the signal handler for the real-time signal with signum num
.
The value of num
must be within [SIGRTMIN
, SIGRTMAX
] range.
Safety
This is considered unsafe because the given handler will be called asynchronously, interrupting whatever the thread was doing and therefore must only do async-signal-safe operations.
