WODM_GETPOS

This message is sent to a waveform output device driver to request the current playback position for a waveform. The playback position is relative to the beginning of the waveform and is reset with the WODM_OPEN and WODM_RESET messages.

Parameters

DWORD dwParam1

Specifies a far pointer to an MMTIME structure.

DWORD dwParam2

Specifies the size of the MMTIME structure.

Return Value

The return value is an error code, or zero (MMSYSERR_NOERROR) if the operation is successful. Possible error codes are:

MMSYSERR_NOTENABLED

The driver failed to load or initialize.

Comments

The wType field of the MMTIME structure indicates the time format requested by the client. If the driver cannot support the requested format, it should return the position in a format that it does support, and change the wType field accordingly.
