SDL_DialogFileCallback - Callback used by file dialog functions.

       This datatype is available since SDL 3.2.0.

       The specific usage is described in each function.

       If filelist is:

       • NULL, an error occurred. Details can be obtained with SDL_GetError().

       • A pointer to NULL, the user either didn't choose any file or canceled the dialog.

       •  A  pointer  to  non-NULL, the user chose one or more files. The argument is a null-terminated array of
       pointers to UTF-8 encoded strings, each containing a path.

       The filelist argument should not be freed; it will automatically be freed when the callback returns.

       The filter argument is the index of the filter that was selected, or -1 if no filter was selected  or  if
       the platform or method doesn't support fetching the selected filter.

       In  Android,  the  filelist  are  content://  URIs.  They  should  be  opened using SDL_IOFromFile() with
       appropriate modes. This applies both to open and save file dialog.
