	)

Set conversion function if the parameters match.

This compares the parameters of the conversion function to the parameters in the AudioConvert context. If the parameters do not match, no changes are made to the active functions. If the parameters do match and the alignment is not constrained, the function is set as the generic conversion function. If the parameters match and the alignment is constrained, the function is set as the optimized conversion function.

Parameters

ac	AudioConvert context
out_fmt	output sample format
in_fmt	input sample format
channels	number of channels, or 0 for any number of channels
ptr_align	buffer pointer alignment, in bytes
samples_align	buffer size alignment, in samples
descr	function type description (e.g. "C" or "SSE")
conv	conversion function pointer
