| /* Description: This tests the rt_sigprocmask() syscall */ |
| /* 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. */ |
| /* */ |
| /* Usage: <for command-line> */ |
| /* rt_sigprocmask01 [-c n] [-e][-i n] [-I x] [-p x] [-t] */ |
| /* where, -c n : Run n copies concurrently. */ |
| /* -e : Turn on errno logging. */ |
| /* -i n : Execute test n times. */ |
| /* -I x : Execute test for x seconds. */ |
| /* -P x : Pause for x seconds between iterations. */ |
| /* -t : Turn on syscall timing. */ |
| /* */ |
| /* Total Tests: 1 */ |
