extern int x1f4_ofit_lxfile
(void *lxfile, void *file, void *data, void *text,
const struct x1f4_sffile_type *sffile);
The x1f4_ifit_lxfile function refits the file object for writing,
with data and text operating contexts and sffile operating
methods. lxfile is expected the file library object for which the
file object was created.
The sffile operating methods will have their first argument of the
struct x1f4_cdfile_type layout. The data and text fields
of the record will match the data and text operating contexts.
file is assumed opened.
Apart from installing the new operating methods (and their contexts), the function only resets the file state (internal buffers, etc).
The function returns 0 for success, one of the defined error codes for
failure.
