NAME

Thread::SigMask - Thread specific signal masks

VERSION

Version 0.001

SYNOPSIS

    use Thread::SigMask qw/sigset/;
	use POSIX qw/SIG_BLOCK SIG_UNBLOCK/;
	
    sigmask(SIG_BLOCK, $sigset);
	...
    sigmask(SIG_UNBLOCK, $sigset);

DESCRIPTION

This module provides per-thread signal masks. On non-threaded perl's, it will be effectively the same as POSIX::sigprocmask. The interface works exactly the same as sigprocmask.

SUBROUTINES

sigmask($how, $newset, $oldset = undef)

Change and/or examine calling process's signal mask. This uses POSIX::SigSet objects for the newset and oldset arguments. The behavior of the call is dependent on the value of how.

  • SIG_BLOCK

    The set of blocked signals is the union of the current set and the set argument.

  • SIG_UNBLOCK

    The signals in set are removed from the current set of blocked signals. It is permissible to attempt to unblock a signal which is not blocked.

  • SIG_SETMASK

    The set of blocked signals is set to the argument set.

If oldset is defined, the previous value of the signal mask is stored in oldset. If newset is NULL, then the signal mask is unchanged (i.e., how is ignored), but the current value of the signal mask is nevertheless returned in oldset (if it is not NULL).
