dmicreceive(3dm)
dmICReceive, - transfer output from the image converter
As shipped in IRIX 6.5.19. Unchanged since IRIX 6.5.
NAME dmICReceive, - transfer output from the image converter SYNOPSIS #include <dmedia/dm_imageconvert.h> DMstatus dmICReceive(DMimageconverter converter, DMbuffer *dstBuffer); DESCRIPTION dmICReceive receives the next available output buffer from the image converter. If it succeeds, dstBuffer will point to an output buffer that contains the output bytes, allocated by the image converter. After dmICReceive returns, the caller is automatically attached to the buffer (see dmBuffer(3dm). When dstBuffer is no longer referenced, dmBufferFree must be called to free up the buffer resource. The contents of dstBuffer should not be modified. After dmICReceive returns, dmICGetSrcParams, dmICGetDstParams, and ICGetConvParams can be called to retrieve the parameters that were used to perform the conversion. To determine whether a buffer contains an INTRA, INTER or BETWEEN frame, use dmBufferGetImageType. DIAGNOSTICS If dmICReceive fails, and return DM_FAILURE, dstBuffer is invalid and the caller is not automatically attached to any buffer. dmICReceive can fail under 2 situations: 1. there was no buffer to receive (error code: DM_IC_Q_EMPTY) 2. an error occured during the conversion process. Details of errors can be retrieved by calling dmGetError(3dm).
