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