):cint;

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.

Errno is used to report errors.

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