inlinestatic

Computes maximum number of frames aligned with the source align criteria that can be copied from source to sink, verifying the number of available source frames vs.

free space available in sink.

Parameters

source	the data source
sink	the data sink

Returns

Number of aligned frames available for processing.

source_to_sink_copy()

int source_to_sink_copy	(	struct sof_source *	source,
