Detailed Description

Function Documentation

mmStreamGetPosition()

mm_word mmStreamGetPosition

(

void

)

Get number of samples elapsed since the stream was opened.

The 32-bit value will wrap every 36 hours or so (at 32khz).

Returns

The nummber of samples.

mmStreamOpen()

void mmStreamOpen

(

mm_stream *

stream

)

Opens an audio stream.

See the tutorials for more information.

Note

You need to initialize Maxmod even if you don't plan on using any soundbank. If that's your situation, use mmInitNoSoundbank().

Warning

If you have some heavy interrupt-routines that are enabled while calling this function, you may corrupt the stream. The function cannot disable interrupts internally because it requires the communications to be active.

Parameters

stream

Pointer to a structure containing information about how the stream will operate.

mmStreamUpdate()

void mmStreamUpdate

(

void

)

Check buffering state and fill stream with data.

Requests will be made to your callback to fill parts of the wave buffer(s). This function only needs to be called manually if the stream isn't in auto-fill mode. This function shouldn't be used when the stream is automatically filled.
