EPOLL_WAIT(3C)							EPOLL_WAIT(3C)

NAME
       epoll_wait, epoll_pwait - wait for epoll events

SYNOPSIS
       #include <sys/epoll.h>

       int epoll_wait(int epfd, struct epoll_event *events,
	    int maxevents, int timeout);

       int epoll_pwait(int epfd, struct epoll_event *events,
	    int maxevents, int timeout,
	    const sigset_t *sigmask);

DESCRIPTION
       The  epoll_wait()  function  waits  for events on the epoll(5) instance
       specified by epfd.  The events parameter must point to an array of max‐
       events epoll_event structures to be filled in with pending events.  The
       timeout argument specifies the number of milliseconds to	 wait  for  an
       event if none is pending.  A timeout of -1 denotes an infinite timeout.

       The  epoll_pwait()  is similar to epoll_wait(), but takes an additional
       sigmask	argument  that	specifies  the	desired	  signal   mask	  when
       epoll_pwait()  is  blocked.  It is equivalent to atomically setting the
       signal mask, calling epoll_wait(), and restoring the signal  mask  upon
       return, and is therefore similar to the relationship between select(3C)
       and pselect(3C).

RETURN VALUES
       Upon successful completion, epoll_wait() and epoll_pwait()  return  the
       number  of  events,  or	0 if none was pending and timeout milliseconds
       elapsed.	 If an error occurs, -1 is returned and errno is set to	 indi‐
       cate the error.

ERRORS
       The epoll_wait() and epoll_pwait() functions will fail if:

       EBADF
		 epfd is not a valid file descriptor.

       EFAULT
		 The  memory  associated with events was not mapped or was not
		 writable.

       EINTR
		 A  signal   was   received   during   the   epoll_wait()   or
		 epoll_pwait().

       EINVAL
		 Either	 epfd is not a valid epoll(5) instance or maxevents is
		 not greater than zero.

NOTES
       The epoll(5) facility is implemented for purposes of offering  compati‐
       bility  for  Linux-borne	 applications; native applications should con‐
       tinue to prefer using event ports via the  port_create(3C),  port_asso‐
       ciate(3C)  and port_get(3C) interfaces.	See epoll(5) for compatibility
       details and restrictions.
