.\"O .SS History
.SS Îò»Ë
.\"O The classical BSD version of this function appeared in 4.2BSD.
.\"O It sets the process's signal mask to
.\"O .IR sigmask .
.\"O Unix95 standardized the incompatible System V version of
.\"O this function, which removes only the specified signal
.\"O .I sig
.\"O from the process's signal mask.
.\"O .\" __xpg_sigpause: Unix 95, spec 1170, SVID, SVr4, XPG
.\"O The unfortunate situation with two incompatible functions with the
.\"O same name was solved by the
.\"O .BR \%sigsuspend (2)
.\"O function, that takes a
.\"O .I "sigset_t *"
.\"O argument (instead of an
.\"O .IR int ).
