Waveform Output Driver Messages (Windows Embedded CE 6.0)
1/6/2010
The following table shows the waveform output driver messages (WODM_XXX).
| Programming element | Description |
|---|---|
This message is used to request a waveform output driver to break an output loop that was created with a WODM_WRITE message. |
|
This message is used to request a waveform output driver to close a specified stream that was previously opened with a WODM_OPEN message. |
|
This message is used to request a waveform output driver to return the capabilities of a specified device. |
|
This message is used in an MMDRV_MESSAGE_PARAMS structure passed to the WAV_IOControl function to request a waveform output driver to return the extended capabilities of a specified device. |
|
This message is used to request a waveform output driver to return the number of device instances that it supports. |
|
This message is used to request a waveform output driver to return the specified device's current pitch multiplier value. |
|
This message is to request a waveform output driver to return the current playback rate multiplier value for the specified device. |
|
This message is used to return the current position within a stream. The position is relative to the beginning of the waveform. |
|
This message is used to request the properties of a waveform output driver. |
|
This message is used to request a waveform output driver to return the current volume level setting for the specified device or stream. |
|
This message is used to request a waveform output driver to open a stream on the specified device. |
|
This message is used to request a waveform output driver to pause playback of a waveform. |
|
This message is used to request a waveform output driver to prepare a system-exclusive data buffer for output. |
|
This message is used to request a waveform output driver to stop sending output data and return all output buffers to the list. |
|
This message is used to request a waveform output driver to continue playback of a waveform after playback has been paused with WODM_PAUSE. |
|
This message is used to request a waveform output driver to set the specified device's pitch multiplier value. |
|
This message is used to request a waveform output driver to set the playback rate multiplier value for the specified device. |
|
This message isused to request a waveform output driver to change properties. |
|
This message is used to request a waveform output driver to set the playback rate multiplier value for the specified device. |
|
This message is used to request a waveform output driver to remove the buffer preparation performed in response to WODM_PREPARE. |
|
This message is used to request a waveform output driver to write a waveform data block to the specified device. |
