[Texmacs-dev] Deprecate FullName.exe

[Darcy Shen]

Since SVN revision 13808, we do not need FullName.exe to get the full name of the user any more on Windows.

I tried using GetUserNameEx to get the full name of the login user, but failed.

And finally, I googled about how to get the full name using Python. Verified with the python snippets in the TeXmacs Python session:

import ctypes
 
def get_display_name():
    GetUserNameEx = ctypes.windll.secur32.GetUserNameExW
    NameDisplay = 3
 
    size = ctypes.pointer(ctypes.c_ulong(0))
    GetUserNameEx(NameDisplay, None, size)
 
    nameBuffer = ctypes.create_unicode_buffer(size.contents.value)
    GetUserNameEx(NameDisplay, nameBuffer, size)
    return nameBuffer.value

It turns out that we need to call GetUserNameEx twice to make the C++ code work!!!

Python win32 api seems to be a good way to expore Windows API before coding in C++.
