al_create_native_file_dialog

ALLEGRO_FILECHOOSER *al_create_native_file_dialog(
   char const *initial_path,
   char const *title,
   char const *patterns,
   int mode)

Introduced in 5.0.0

Creates a new native file dialog. You should only have one such dialog opened at a time.

Parameters:

initial_path: The initial search path and filename. Can be NULL. To start with a blank file name the string should end with a directory separator (this should be the common case).
title: Title of the dialog.
patterns: A list of semi-colon separated patterns to match. You should always include the pattern "*.*" as usually the MIME type and not the file pattern is relevant. If no file patterns are supported by the native dialog, this parameter is ignored.
mode: 0, or a combination of the flags below.

Possible flags for the 'flags' parameter are:

ALLEGRO_FILECHOOSER_FILE_MUST_EXIST: If supported by the native dialog, it will not allow entering new names, but just allow existing files to be selected. Else it is ignored.
ALLEGRO_FILECHOOSER_SAVE: If the native dialog system has a different dialog for saving (for example one which allows creating new directories), it is used. Else ignored.
ALLEGRO_FILECHOOSER_FOLDER: If there is support for a separate dialog to select a folder instead of a file, it will be used.
ALLEGRO_FILECHOOSER_PICTURES: If a different dialog is available for selecting pictures, it is used. Else ignored.
ALLEGRO_FILECHOOSER_SHOW_HIDDEN: If the platform supports it, also hidden files will be shown.
ALLEGRO_FILECHOOSER_MULTIPLE: If supported, allow selecting multiple files.

Returns:

A handle to the dialog which you can pass to al_show_native_file_dialog to display it, and from which you then can query the results. When you are done, call al_destroy_native_file_dialog on it.

If a dialog window could not be created then this function returns NULL.
