capDriverGetVersion

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

BOOL capDriverGetVersion(
  hwnd,  
  szVer, 
  wSize  
);
 

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.
