|
c |
A cursor handle returned from a cursor or index search function |
|
code |
The address of a uint2 variable to receive the class code |
This function returns the class code of the object at the current cursor position.
| MCO_S_OK | Class code returned successfully |
|
MCO_E_CURSOR_INVALID |
Cursor not positioned to an object |
