Instructions for adding a Win32 API function to CmUtoA
======================================================
Note that all the files referenced below contain functions or declarations in alphabetical order.
This sort order should be maintained.
For these instructions, I will use an imaginary Win32 API function named DoSomething.
In cm\common\inc\cmutoa.h
=========================
(a) search \nt\public\sdk\inc\*.h for the 'W' version of the function declaration, and copy it into
the declarations section at the top, then modify to match the surrounding functions.
(b) Add an entry within the _tagUAPIInit union.
(c) Increment the size of ppvUapiFun by 1.
In cm\common\inc\uapi.h
=======================
add an extern declaration for DoSomethingU.
In cm\uapi\uapiinit\uapiinit.cpp
================================
(a) add a declaration for DoSomethingU
(b) add the function check to the big return statement in CheckUAPIFunctionPointers
(c) add the assignment for DoSomethingU to both the 'then' and 'else' portions of the
if (IsWindowsNT) statement in InitUnicodeAPI.
In cm\uapi\cmutoa\cmutoa.cpp
============================
(a) add an initialization line to InitCmUToA
(b) create the wrapper function DoSomethingAU in this file (maintain sort order).
