rt_sigprocmask − Change the list of currently blocked signals
|
long sys_rt_sigprocmask (sigset_t *set, sigset_t *oset, size_t sigsetsize); |
rt_sigprocmask
changes the list of currently blocked signals. The
set value stores the signal mask of the pending
signals. The previous action on the signal is saved in
oact. The value of how indicates how the call
should behave; its values are as follows:
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 okay to unblock a signal that is not blocked.
SIG_SETMASK
The set of blocked signals is set to the set argument. sigsetsize should indicate the size of a sigset_t type.
rt_sigprocmask returns 0 on success; otherwise, rt_sigprocmask returns one of the errors listed in the "Errors" section.
-EINVAL
sigsetsize was not equivalent to the size of a sigset_t type.
-EFAULT
An invalid set, act, or oact was specified.
