*** 10,21 **** .\" .TH EPOLL_CREATE 3C "April 9, 2016" .SH NAME epoll_create, epoll_create1 \- create an epoll instance .SH SYNOPSIS - - .LP .nf #include <sys/epoll.h> \fBint\fR \fBepoll_create\fR(\fBint\fR \fIsize\fR); .fi --- 10,19 ----
*** 24,34 **** .nf \fBint\fR \fBepoll_create1\fR(\fBint\fR \fIflags\fR); .fi .SH DESCRIPTION - .LP The \fBepoll_create()\fR and \fBepoll_create1()\fR functions both create an \fBepoll\fR(5) instance that can be operated upon via \fBepoll_ctl\fR(3C), \fBepoll_wait\fR(3C) and \fBepoll_pwait\fR(3C). \fBepoll\fR instances are represented as file descriptors, and should be closed via \fBclose\fR(2). --- 22,31 ----
*** 47,61 **** Instance should be closed upon an \fBexec\fR(2); see \fBopen\fR(2)'s description of \fBO_CLOEXEC\fR. .RE .SH RETURN VALUES - .LP Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error. .SH ERRORS - .LP The \fBepoll_create()\fR and \fBepoll_create1()\fR functions will fail if: .sp .ne 2 .na \fB\fBEINVAL\fR\fR --- 44,56 ----
*** 84,99 **** The maximum allowable number of files is currently open in the system. .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_ctl\fR(3C), \fBepoll_wait\fR(3C), \fBepoll\fR(5) --- 79,91 ----
