* History:
|
|
*
|
|
* Created 12-Apr-1991 by Nigel Thompson (nigelt)
|
|
* Much hacked about version of the Win 3.1 rmload.c source
|
|
* It doesn't attempt any device driver resource loading
|
|
* or do anything to support Win 2.x apps.
|
|
*
|
|
* Revised 19-May-1991 by Jeff Parsons (jeffpar)
|
|
* IFDEF'ed everything except LoadString; because of the client/server
|
|
* split in USER32, most resources are copied to the server's context and
|
|
* freed in the client's, meaning the client no longer gets a handle to
|
|
* a global memory object. We could give it one, but it would be a separate
|
|
* object, which we would have to keep track of, and which would be difficult
|
|
* to keep in sync with the server's copy if changes were made.
