Function nix::sys::signalfd::signalfd

pub fn signalfd(fd: RawFd, mask: &SigSet, flags: SfdFlags) -> Result<RawFd>

Creates a new file descriptor for reading signals.

Important: please read the module level documentation about signal discarding before using this function!

The mask parameter specifies the set of signals that can be accepted via this file descriptor.

A signal must be blocked on every thread in a process, otherwise it won’t be visible from signalfd (the default handler will be invoked instead).

See the signalfd man page for more information
