/* Wine doesn't use the way WinHelp API sends information in Windows, because:
* 1/ it's not consistent acrosss Win9x, NT...
* 2/ NT implementation is not yet fully understood (and includes some shared
* memory mechanism)
* 3/ uses a dynamically allocated message number (WM_WINHELP), which
* obfuscates the code
*
* So we use (for now) the simple protocol:
* 1/ it's based on copy data
* 2/ we tag the message with a magic number, to make it a bit more robust
* (even if it's not 100% safe)
* 3/ data structure (WINHELP) has the same layout that the one used on Win95.
* This doesn't bring much, except not going to far away from real
* implementation.
*
* This means anyway that native winhelp.exe and winhlp32.exe cannot be
* called/manipulated from WinHelp API.
