poll

poll.h(3HEAD)							      Headers							     poll.h(3HEAD)

NAME

       poll.h, poll - definitions for the poll() function

SYNOPSIS

       #include <poll.h>

DESCRIPTION

       The <poll.h> header defines the pollfd structure, which includes the following members:

       int fd	       the following descriptor being polled

       short events    the input event flags (see below)

       short revents   the output event flags (see below)

       The <poll.h> header defines the following type through typedef:

       nfds_t	       an unsigned integer type used for the number of file descriptors

       The  implementation  supports  one or more programming environments in which the width of nfds_t is no greater than the width of type long.
       The names of these programming environments can be obtained using the confstr() function or the getconf utility. See confstr(3C)  and  get-
       conf(1).

       The  following  symbolic  constants  are defined, zero or more of which can be OR'ed together to form the events or revents members  in the
       pollfd structure:

       POLLIN	       Data other than high-priority data can be read without blocking.

       POLLRDNORM      Normal data can be read without blocking.

       POLLRDBAND      Priority data can be read without blocking.

       POLLPRI	       High priority data can be read without blocking.

       POLLOUT	       Normal data can be written without blocking.

       POLLWRNORM      Equivalent to POLLOUT.

       POLLWRBAND      Priority data can be written.

       POLLERR	       An error has occurred (revents only).

       POLLHUP	       Device has been disconnected (revents only).

       POLLNVAL        Invalid fd member (revents only).

       The significance and semantics of normal, priority, and high-priority data are file and device-specific.
