capSetCallbackOnError
The capSetCallbackOnError macro sets an error callback function in the client application. AVICap calls
this procedure when errors occur. You can use this macro or explicitly call
the WM_CAP_SET_CALLBACK_ERROR message.
BOOL capSetCallbackOnError(
Parameters
hwnd
Handle of a capture window.
fpProc
Address of the error callback function. Specify NULL for this parameter to
disable a previously installed error callback function.
Return Values
Returns TRUE if successful or FALSE if streaming capture or a single-frame
capture session is in progress.
Remarks
Applications can optionally set an error callback function. If set, AVICap
calls the error procedure in the following situations:
- The disk is full.
- A capture window cannot be connected with a capture driver.
- A waveform-audio device cannot be opened.
- The number of frames dropped during capture exceeds the specified percentage.
- The frames cannot be captured due to vertical synchronization interrupt
problems.
