) -> i32

Available on crate feature AudioFile only.

Parameter inPropertyID: an AudioFileGlobalInfo property constant.

Parameter inSpecifierSize: The size of the specifier data.

Parameter inSpecifier: A specifier is a buffer of data used as an input argument to some of the global info properties.

Parameter ioDataSize: on input the size of the outPropertyData buffer. On output the number of bytes written to the buffer.

Parameter outPropertyData: the buffer in which to write the property data.

Returns: returns noErr if successful.
