These function are only useful for Windows, but they can be used without error on other platform for making platform-independent code that has an additional behaviour under Windows. On the other platforms, these function just return NULL silently.

tk2ico.create(iconfile, res = 0, size = 16)
tk2ico.destroy(icon)
tk2ico.list(file = "shell32.dll")
tk2ico.sizes(file = "shell32.dll", res = "application")
tk2ico.load(file = "shell32.dll", res = "application", size = 16)
tk2ico.set(win, icon, pos = NULL, type = c("all", "small", "big"))
tk2ico.setFromFile(win, iconfile)

## Deprecated functions since drop of winico.dll support
tk2ico.hicon(icon)
tk2ico.info(icon, convert = TRUE)
tk2ico.text(icon)
tk2ico.text(icon) <- value
tk2ico.pos(icon) <- value
tk2ico.taskbar.add(icon, pos = 0, text = tk2ico.text(icon),
    leftmenu = NULL, rightmenu = NULL)
tk2ico.taskbar.delete(icon)
tk2ico.taskbar.modify(icon, pos = NULL, text = NULL)

`iconfile`	a file with a .ico, or .exe extension, containing one or more Windows icons
`file`	a file having icon resources (.exe, or .dll)
`res`	the name of the resource from where the icon should be extracted
`size`	the size of the icon to use. For windows icons, 16 should be fine usually
`win`	a Tk window, or an integer representing the handle (HWND) of a foreign window whose icon will be changed (take care, the function returns `TRUE` even if the handle is wrong!
`icon`	an icon object.
`convert`	do we convert the result into a data.frame?
`pos`	a position (starting from 0) pointing to an icon in a multi-icon object. Note that `pos` is not used in `tk2ico.set()` if `type = "all"` (in this case, best icons matching both \"small\" and \"large\" sizes are searched in the `icon` resource.
`type`	do we change only the small, the large, or both icons?
`value`	a string with the new text for the icon in `tk2ico.text()` or a numerical value indicating the new default position in the icon resource for `tk2ico.pos()`.
`text`	change a text for an icon.
`leftmenu`	a \"tkwin\" object to display when the user left-clicks on the taskbar icon (usually, a Tk popup menu), or `NULL` for nothing.
`rightmenu`	idem as \'lefmenu\' but for a right-click on the taskbar icon.
