WM_CAP_SET_CALLBACK_ERROR
The WM_CAP_SET_CALLBACK_ERROR message sets an error callback function in the
client application. AVICap calls this procedure when errors occur. You can send
this message explicitly or by using the capSetCallbackOnError macro.
WM_CAP_SET_CALLBACK_ERROR
wParam = (WPARAM) 0;
lParam = (LPARAM) (LPVOID) (fpProc);
Parameters
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.
