Function MusicSequenceFileCreateData 

pub unsafe extern "C-unwind" fn MusicSequenceFileCreateData(
    in_sequence: MusicSequence,
    in_file_type: MusicSequenceFileTypeID,
    in_flags: MusicSequenceFileFlags,
    in_resolution: i16,
    out_data: NonNull<*const CFData>,
) -> i32

Available on crate features MusicPlayer and objc2-core-foundation only.

Create a data object from a sequence

The same basic parameters apply to this as with the MusicSequenceFileCreate function. The difference being that that function will create a file on disk, whereas this one will create a CFData object that is a file in memory. The CFData object should be released by the caller.

Parameter inSequence: the sequence

Parameter inFileType: the type of file to create

Parameter inFlags: flags to control the file creation

Parameter inResolution: the resolution (depending on file type and sequence type)

Parameter outData: the resulting data object

Safety

• in_sequence must be a valid pointer.
• out_data must be a valid pointer.
