dmFXGetDMBuffer(3dm)					  dmFXGetDMBuffer(3dm)

NAME
     dmFXGetDMBuffer - return the DMbuffer associated with a DMfxbuffer

SYNOPSIS
     #include <dmedia/fx_buffer.h>

     DMstatus dmFXGetDMBuffer
	   ( DMfxbuffer* fxbuffer,
	     DMbuffer*	 returnDMBuffer,
	     DMparams**	 returnFormat )

PARAMETERS
     fxbuffer	      A buffer that was created with dmFXAllocateImageBuffers.

     returnDMBuffer   A pointer to a DMbuffer* to fill in.

DESCRIPTION
     Some implementations of DMfxbuffers use DMbuffers internally to hold
     images.  An application can get a pointer to this DMbuffer, if there is
     one, by calling dmFXGetDMBuffer.

     If there is an a DMbuffer associated with fxbuffer, then returnDMBuffer
     will be set, returnFormat will be set to describe the format of the image
     in the buffer, and DM_SUCCESS will be returned.  Both returnDMBuffer and
     returnFormat are valid only until the next operation on the same
     DMfxbuffer.

     If there is no associated DMbuffer, then DM_FAILURE is returned.

SEE ALSO
     dmFXAllocateImageBuffers(3dm), DMbuffer(4).
