Function register_rt_signal_handler

Source 
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.

ยงSafety

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.
