- SIGPROCMASK(2) Minix Programmer's Manual SIGPROCMASK(2)
- NAME
- sigprocmask - manipulate the signal mask
- SYNOPSIS
- #include <signal.h>
- int sigprocmask(int how, const sigset_t *set, sigset_t *oset)
- DESCRIPTION
- Sigprocmask() examines or manipulates the signal mask. This mask is the
- set of signals that are currently blocked. The how argument determines
- the action that must be performed. In all cases the signal set
- referenced by oset, if not NULL, will be used to receive the old signal
- mask. The set argument, if not NULL, will be used to set or modify the
- current signal mask.
- How can be one of:
- SIG_BLOCK Add the signals referenced by set to the mask.
- SIG_UNBLOCK Remove the signals referenced by set from the mask.
- SIG_SETMASK Set the signal mask to the set referenced by set.
- The value of how is ignored if set is NULL.
- SEE ALSO
- sigaction(2), sigpending(2), sigsuspend(2), sigset(3).
- DIAGNOSTICS
- Returns 0 on success and -1 on error. The error code is EFAULT for a bad
- set or oset address, or EINVAL for a bad how argument.
