Description

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 nset argument.
SIG_UNBLOCK
The signals in nset are removed from the set of currently blocked signals.
SIG_SETMASK
The list of blocked signals is set so nset.

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