 * GUIGetFileName

 * returns: OFN_RC_FAILED_TO_INITIALIZE
 *          OFN_RC_NO_FILE_SELECTED
 *          OFN_RC_FILE_SELECTED
 *          OFN_RC_RUNTIME_ERROR
 *
 * open_file_name structure
 * ------------------------
 *
 * filter_list - a set of null delimited string pairs describing the files
 *               that can be edited.  The first string in the pair is
 *               a description, the second string is a wild card.  The
 *               second string may contain semicolons to separate multiple
 *               wild cards.  The list must be terminated by two null chars.
 *               For example:
 *                      char *filterList =
 *                              "Text Files\0*.txt\0" \
 *                              "All Files\0*.*\0" \
 *                              "Source files\0*.c;*.h;*.cpp;*.hpp;*.asm\0" \
 *                              "\0";
 *
 * filter_index - a zero-based index, indicating which of the items in
 *                the filter list will be displayed when the dialog is
 *                created.
 *
 * file_name - a pointer to a buffer for storing the fully qualified path
 *             of the file that the user selects.  May be NULL if this
 *             is not desired.
 *
 * max_file_name - the length of the file_name buffer.
 *
 * base_file_name - a pointer to a buffer for storing the file name and
 *                  extension of the file that the user selects.  May be NULL
 *                  if this is not desired.
 *
 * max_base_file_name - the length of the base_file_name buffer.
 *
 * title - the title to be assigned to to dialog
 *
 * flags - flags to control the behavior of the dialog.  They are:
 *              OFN_OVERWRITEPROMPT - prompts the user if he selects a file
 *                                    that already exists
 *              OFN_HIDEREADONLY    - read only files will not be displayed.
 *              OFN_CHANGEDIR       - once the dialog is exited, the working
 *                                    directory will be the home directory
 *                                    of the selected file.
 *              OFN_ISSAVE          - getting a file name for saving
 *
 * initial_dir - used to specify the starting directory.  Using NULL will
 *               cause the current directory to be the starting directory.
 *
 * wnd - the parent window of the dialog.
 *
