	Quick Info

The WM_CAP_DRIVER_GET_VERSION message returns the version information of the capture driver connected to a capture window. You can send this message explicitly or by using the capDriverGetVersion macro.

wParam = (WPARAM) (wSize);

lParam = (LPARAM) (LPVOID) (LPSTR) (szVer);

Parameters
wSize

Size, in bytes, of the application-defined buffer referenced by szVer.

szVer

Address of an application-defined buffer used to return the version information as a null-terminated string.

Return Values
Returns TRUE if successful or FALSE if the capture window is not connected to a capture driver.

Remarks
The version information is a text string retrieved from the driver's resource area. Applications should allocate approximately 40 bytes for this string. If version information is not available, a NULL string is returned.
