Available on crate feature
signal only.Expand description
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).
