34/* Notes:
35 * MS uses a critical section at a few locations. However, I fail to
36 * see the reason for this. Their comdlg32.dll has a few race conditions
37 * but _not_ at those places that are protected with the mutex (there are
38 * globals that seem to hold info for the wndproc).
39 *
40 * FindText32x/ReplaceText32x
41 * The find/replace calls are passed a structure that is _not_ used
42 * internally. There is a local copy that holds the running info to
43 * be able to combine xxx32A and xxx32W calls. The passed pointer is
44 * returned upon sendmessage. Apps wont break this way when they rely
45 * on the original pointer. This will work as long as the sizes of
46 * FINDREPLACE32A == FINDREPLACE32W. The local copy will also prevent
47 * the app to see the wine-specific extra flags to distinguish between
48 * A/W and Find/Replace.
