As shipped in IRIX 6.5. First release of IRIX 6.5.
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.
