SigProcMask

Set list of blocked signals

Declaration

Source position: oldlinux.pp line 1481

procedure SigProcMask(

How: LongInt;

SSet: PSigSet;

OldSSet: PSigSet

);

Changes the list of currently blocked signals. The behaviour of the call depends on How :

SIG_BLOCK: The set of blocked signals is the union of the current set and the SSet argument.
SIG_UNBLOCK: The signals in SSet are removed from the set of currently blocked signals.
SIG_SETMASK: The list of blocked signals is set so SSet.

If OldSSet is non-nil, then the old set is stored in it.

LinuxError is used to report errors.

sys_efault: SSet or OldSSet point to an adress outside the range of the process.
sys_eintr: System call was interrupted.
