48 * MS uses a critical section at a few locations. However, I fail to
49 * see the reason for this. Their comdlg32.dll has a few race conditions
50 * but _not_ at those places that are protected with the mutex (there are
51 * globals that seem to hold info for the wndproc).
53 * FindText[AW]/ReplaceText[AW]
54 * The find/replace calls are passed a structure that is _not_ used
55 * internally. There is a local copy that holds the running info to
56 * be able to combine xxxA and xxxW calls. The passed pointer is
57 * returned upon sendmessage. Apps won't break this way when they rely
58 * on the original pointer. This will work as long as the sizes of
59 * FINDREPLACEA == FINDREPLACEW. The local copy will also prevent
60 * the app to see the wine-specific extra flags to distinguish between
61 * A/W and Find/Replace.
