	Quick Info

The WM_CAP_DRIVER_GET_NAME message returns the name of the capture driver connected to the capture window. You can send this message explicitly or by using the capDriverGetName macro.

wParam = (WPARAM) (wSize);

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

Parameters
wSize

Size, in bytes, of the buffer referenced by szName.

szName

Address of an application-defined buffer used to return the device name 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 name is a text string retrieved from the driver's resource area. Applications should allocate approximately 80 bytes for this string. If the driver does not contain a name resource, the full path name of the driver listed in the registry or in the SYSTEM.INI file is returned.
