DMNETDATAFD(3dm)					      DMNETDATAFD(3dm)

NAME    [Toc]    [Back]

     dmNetDataFd - return FD associated	with a DMNetConnection

SYNOPSIS    [Toc]    [Back]

     #include <dmedia/dmnet.h>

     int dmNetDataFd(DMNetConnection);

DESCRIPTION    [Toc]    [Back]

     dmNetDataFd returns a file	descriptor associated with the specified
     DMNetConnection. This descriptor is suitable for use by select() to
     signify the availability of incoming data.

DIAGNOSTICS    [Toc]    [Back]

     dmNetDataFd returns DM_FAILURE if the DMNetConnection was not valid.

NOTE    [Toc]    [Back]

     Depending on the underlying transport mechanism, the file descriptor
     returned by dmNetDataFd may indicate as ready to read (via	select)	when a
     complete DMbuffer is ready, or merely when	the first part of the data
     that makes	up a DMbuffer has arrived on the network connection.  Thus,
     even though the DMNetConnection is	ready, dmNetRecv may not return	data
     immediately when it is called.

CAVEAT    [Toc]    [Back]

     The dmNetControFd function	is now deprecated.
