Object handles are stored in the bit maps when they are created. Calling SetDriverInfo provides a method the presentation driver can use to change the driver handle in the bit map. SetDriverInfo includes a check to ensure that the object is, or was created by, an instance of a DC for the same device as the DC identified by hdc. If the check is not successful, the function returns GPI_ALTERROR.

SetDriverInfo is exported by the graphics engine at ordinal 31. If a presentation driver calls this function, it must be imported by the driver's module definition file.
