*** 10,21 **** .\" .TH EPOLL_WAIT 3C "Apr 17, 2014" .SH NAME epoll_wait, epoll_pwait \- wait for epoll events .SH SYNOPSIS - - .LP .nf #include <sys/epoll.h> \fBint\fR \fBepoll_wait\fR(\fBint\fR \fIepfd\fR, \fBstruct epoll_event *\fR\fIevents\fR, \fBint\fR \fImaxevents\fR, \fBint\fR \fItimeout\fR); --- 10,19 ----
*** 27,37 **** \fBint\fR \fImaxevents\fR, \fBint\fR \fItimeout\fR, \fBconst sigset_t *\fR\fIsigmask\fR); .fi .SH DESCRIPTION - .LP The \fBepoll_wait()\fR function waits for events on the \fBepoll\fR(5) instance specified by \fIepfd\fR. The \fIevents\fR parameter must point to an array of \fImaxevents\fR \fIepoll_event\fR structures to be filled in with pending events. The \fItimeout\fR argument specifies the number of milliseconds to wait for an event if none is pending. A --- 25,34 ----
*** 43,60 **** setting the signal mask, calling \fBepoll_wait()\fR, and restoring the signal mask upon return, and is therefore similar to the relationship between \fBselect\fR(3C) and \fBpselect\fR(3C). .SH RETURN VALUES - .LP Upon successful completion, \fBepoll_wait()\fR and \fBepoll_pwait()\fR return the number of events, or 0 if none was pending and \fItimeout\fR milliseconds elapsed. If an error occurs, -1 is returned and errno is set to indicate the error. .SH ERRORS - .LP The \fBepoll_wait()\fR and \fBepoll_pwait()\fR functions will fail if: .sp .ne 2 .na \fB\fBEBADF\fR\fR --- 40,55 ----
*** 91,108 **** is not greater than zero. .RE .sp .SH NOTES - .LP - The \fBepoll\fR(5) facility is implemented for purposes of offering compatibility for Linux-borne applications; native applications should continue to prefer using event ports via the \fBport_create\fR(3C), \fBport_associate\fR(3C) and \fBport_get\fR(3C) interfaces. See \fBepoll\fR(5) for compatibility details and restrictions. .SH SEE ALSO - .LP \fBepoll_create\fR(3C), \fBepoll_ctl\fR(3C), \fBport_create\fR(3C), \fBport_associate\fR(3C), \fBport_get\fR(3C), \fBpselect\fR(3C), \fBepoll\fR(5) --- 86,100 ----
