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(
|
hwnd, |
|
|
fpProc |
|
|
); |
|
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.
