Changes

Changelog for Win32 package

2.13.4.0 October 2022

  • Add support for semaphores with System.Win32.Semaphore (See #214).
  • Add function createFile_NoRetry (see #208)
  • The type signatures for loadLibrary and loadLibraryEx now refer to HMODULE instead of HINSTANCE for consistency with the official Win32 API documentation. Note that HMODULE and HINSTANCE are both type synonyms for the same thing, so this only changes the presentation of these functions’ type signatures, not their behavior.

  • Renamed fields of COORD and SMALL_RECT to avoid name clashes. (See #157)

2.9.0.0 June 2020

  • setWindowClosure now returns the old window closure.
  • defWindowProc now assumes the data stored in GWLP\_USERDATA is the window closure (in line with setWindowClosure and the supplied C genericWndProc)
