The following table shows the waveform input driver messages (WIDM_XXX).
| Programming element | Description |
|---|---|
This message is used to request a waveform input driver to add an empty input buffer to its input buffer queue. |
|
This message is used to request a waveform input driver to close a specified device instance previously opened with WIDM_OPEN. |
|
This message is used to request a waveform input driver to return the capabilities of a specified device. |
|
This message is used to request a waveform input driver to return the number of devices that it supports. |
|
This message is used to request a stream input driver to return the current input position within a waveform. The input position is relative to the first recorded sample of the waveform. |
|
This message is used to reqest the properties of a waveform input driver. |
|
This message is used to request a waveform input driver to open a stream of a specified device. |
|
This message is used to request a waveform input driver to prepare a system-exclusive data buffer for input. |
|
This message is used to request a waveform input driver to stop recording and return all buffers in the input queue to the caller. |
|
This message isused to request a waveform input driver to change properties. |
|
This message is used to request a waveform input driver to begin recording. |
|
This message is used to request a waveform input driver to stop recording. |
|
This message is used to request a waveform input driver to undo the buffer preparation that was performed in response to a WIDM_PREPARE message. |
