lpDDHELCaps

Address of a DDCAPSstructure that will be filled with the capabilities of the HEL. Set this parameter to NULL if HEL capabilities are not to be retrieved.

Return Values

If the method succeeds, the return value is DD_OK.

If the method fails, the return value may be one of the following error values:
