VLDMBUFFERSEND(3dm)                                        VLDMBUFFERSEND(3dm)



NAME
     vlDMBufferSend - send a DMbuffer to video out.

SYNOPSIS
     #include <dmedia/vl.h>

     int vlDMBufferSend(VLServer svr, VLPath path, DMbuffer dmbuffer);

DESCRIPTION
     vlDMBufferSend puts the DMbuffer on the specified paths output drain
     queue. Care must be taken not to overflow this queue by adding buffers
     faster than the video library can dequeue them and send them out. This
     call should be synchronized with VLTransferComplete events from the path
     which indicates a buffer has been sent out.

DIAGNOSTICS
     vlDMBufferSend returns 0 if successful, otherwise it returns -1 and
     vlErrno is set to indicate the error.

CAVEATS
     This function is obsolete. vlDMBufferPutValid should be used instead.
     See vlintro (3dm) and VLEXTEVENTRECV (3dm).

     When using glXAssociateDMPbufferSGIX to pass DMbuffers between video and
     OpenGL on the O2 platform, VLLAYOUT should be set to VLLAYOUTGRAPHICS.
     This way, the video libary will expect DMbuffers in the format used
     internally by OpenGL.
