to the capture window. You can send this message explicitly or by using the capDriverGetName macro.
WM_CAP_DRIVER_GET_NAME
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.
