From b611967de4dc5c52049676c4369dcac622a7cdfe Mon Sep 17 00:00:00 2001 From: Davide Libenzi Date: Wed, 11 Oct 2006 01:21:44 -0700 Subject: [PATCH] epoll_pwait() Implement the epoll_pwait system call, that extend the event wait mechanism with the same logic ppoll and pselect do. The definition of epoll_pwait is: int epoll_pwait(int epfd, struct epoll_event *events, int maxevents, int timeout, const sigset_t *sigmask, size_t sigsetsize); The difference between the vanilla epoll_wait and epoll_pwait is that the latter allows the caller to specify a signal mask to be set while waiting for events. Hence epoll_pwait will wait until either one monitored event, or an unmasked signal happen. If sigmask is NULL, the epoll_pwait system call will act exactly like epoll_wait. For the POSIX definition of pselect, information is available here: http://www.opengroup.org/onlinepubs/009695399/functions/select.html Signed-off-by: Davide Libenzi Cc: David Woodhouse Cc: Andi Kleen Cc: Michael Kerrisk Cc: Ulrich Drepper Cc: Roland McGrath Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- arch/i386/kernel/syscall_table.S | 1 + 1 file changed, 1 insertion(+) (limited to 'arch') diff --git a/arch/i386/kernel/syscall_table.S b/arch/i386/kernel/syscall_table.S index 7e639f78b0b..2697e9210e9 100644 --- a/arch/i386/kernel/syscall_table.S +++ b/arch/i386/kernel/syscall_table.S @@ -318,3 +318,4 @@ ENTRY(sys_call_table) .long sys_vmsplice .long sys_move_pages .long sys_getcpu + .long sys_epoll_pwait -- cgit v1.2.3
