; Function: Notifies about changes within folders.
; This is a rewrite of HotKeyIt's WatchDirectory() released at
; http://www.autohotkey.com/board/topic/60125-ahk-lv2-watchdirectory-report-directory-changes/
; Tested with: AHK 1.1.23.01 (A32/U32/U64)
; Tested on: Win 10 Pro x64
; Usage: WatchFolder(Folder, UserFunc[, SubTree := False[, Watch := 3]])
; Parameters:
; Folder - The full qualified path of the folder to be watched.
; Pass the string "**PAUSE" and set UserFunc to either True or False to pause respectively resume watching.
; Pass the string "**END" and an arbitrary value in UserFunc to completely stop watching anytime.
; If not, it will be done internally on exit.
; UserFunc - The name of a user-defined function to call on changes. The function must accept at least two parameters:
; 1: The path of the affected folder. The final backslash is not included even if it is a drive's root
; directory (e.g. C:).
; 2: An array of change notifications containing the following keys:
; Action: One of the integer values specified as FILE_ACTION_... (see below).
; In case of renaming Action is set to FILE_ACTION_RENAMED (4).
; Name: The full path of the changed file or folder.
; OldName: The previous path in case of renaming, otherwise not used.
; IsDir: True if Name is a directory; otherwise False. In case of Action 2 (removed) IsDir is always False.
; Pass the string "**DEL" to remove the directory from the list of watched folders.
; SubTree - Set to true if you want the whole subtree to be watched (i.e. the contents of all sub-folders).
; Default: False - sub-folders aren't watched.
; Watch - The kind of changes to watch for. This can be one or any combination of the FILE_NOTIFY_CHANGES_...
; values specified below.
; Default: 0x03 - FILE_NOTIFY_CHANGE_FILE_NAME + FILE_NOTIFY_CHANGE_DIR_NAME
; Return values:
; Returns True on success; otherwise False.
; Change history:
; 1.0.03.00/2021-10-14/just me - bug-fix for addding, removing, or updating folders.
; 1.0.02.00/2016-11-30/just me - bug-fix for closing handles with the '**END' option.
; 1.0.01.00/2016-03-14/just me - bug-fix for multiple folders
; 1.0.00.00/2015-06-21/just me - initial release
; License:
; The Unlicense -> http://unlicense.org/
; Remarks:
; Due to the limits of the API function WaitForMultipleObjects() you cannot watch more than MAXIMUM_WAIT_OBJECTS (64)
; folders simultaneously.
