VLEVENTRECV(3dm)					      VLEVENTRECV(3dm)

NAME
     vlPathGetFD, vlEventRecv, vlEventToDMBuffer - event handling routines

SYNOPSIS
     #include <dmedia/vl.h>

     int vlPathGetFD(VLServer svr, VLPath path, int *ret_fd);
     int vlEventRecv(VLServer svr, VLPath path, VLEvent *evp);
     int vlEventToDMBuffer(VLEvent *evp, DMbuffer *dmbuffer);

DESCRIPTION
     vlPathGetFD returns the file descriptor associated with the specified
     path. This FD can be used in conjuction with a select(2) call for
     notification that events are available for the path.

     vlEventRecv returns the next event queued on the specified path. If no
     event is available vlEventRecv returns -1 and sets vlErrno to VLAgain. If
     the event is a VLTransferComplete event from a video source to a memory
     drain, the event will have a DMBuffer associated with it. This buffer
     must be obtained and released with calls to vlEventToDMBuffer and
     dmBufferFree(3dm).

     vlEventToDMBuffer converts a VLTransferComplete event into a DMBuffer.
     The event must represent a transfer going from a video source to a memory
     drain. An event can only be converted to a DMbuffer once. The DMbuffer is
     released with a call to dmBufferFree(3dm).

DIAGNOSTICS
     All routines return 0 if successful, otherwise -1 is returned and vlErrno
     is set to indicate the error.

CAVEATS
     These functions are obsolete.  vlNextEvent or vlDMBufferGetValid should
     be used instead.
