Function nix::sys::signal::pthread_sigmask
[−]
[src]
pub fn pthread_sigmask(how: HowFlag, set: Option<&SigSet>, oldset: Option<&mut SigSet>) -> Result<()>
Manages the signal mask (set of blocked signals) for the calling thread.
If the set parameter is Some(..), then the signal mask will be updated with the signal set.
The how flag decides the type of update. If set is None, how will be ignored,
and no modification will take place.
If the 'oldset' parameter is Some(..) then the current signal mask will be written into it.
If both set and oldset is Some(..), the current signal mask will be written into oldset,
and then it will be updated with set.
If both set and oldset is None, this function is a no-op.
