win32

Overview

win32 is a library containing a set of CFFI bindings and constant definitions for interacting with the Win32 API. This means it's a practically non-existant layer on top of the API, and has little to no utility other than exposing the raw interface.

Since relatively often type names might be changed around, and because it includes just a random assortment of things as one giant file, I don't recommend using it as a library dependency.

I primarily use this to experiment with some API before using it. That said, hopefully this can be cleaned up to be properly reusable.

Check out winutil to see about calling into win32.

Notes:

BOOL BOOLEAN

The BOOL and BOOLEAN types will be coerced to generalized booleans as per :boolean.

Unicode

When encountering "ANSI" functions with "Unicode" counterparts, the latter will always be used. Bindings that accept strings all use the :utf-16 encoding (little-endian typically, but with guards in the case of big-endian).

When encoding to/from a Win32 string, make use of the `win32:+win32-string-encoding+':

(defun lisp-to-wstring (string wchar-buf wchar-count)
  (cffi:lisp-string-to-foreign
   string
   wchar-buf
   (* wchar-count (cffi:foreign-type-size 'win32:wchar))
   :encoding win32:+win32-string-encoding+))

(defun wstring-to-lisp (wchar-buf wchar-count)
  (values
   (cffi:foreign-string-to-lisp
    wchar-buf
    :count (* wchar-count (cffi:foreign-type-size 'win32:wchar))
    :encoding win32:+win32-string-encoding+)))

C Types

Most of WinAPI is defined in terms of Windows' own types, with well-defined size across ABI's, such as win32:long, win32:char, etc. Occasionally, a type will be a bare C type instead. In this case, the corresponding CFFI type will be used, such as :int or :char

Probable Goals:

Separate into multiple source files and separate packages/systems to have a 1:1 with the library DLLS (user32, gdi32 etc.).
Normalize and stabilize type names to avoid breakage if people use win32 directly.
