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.
