Intended for inputting files of input code. However, 3DLDF does not currently have a routine for reading input code.
in_stream
is currently attached to the file ldfinput.ldf byinitialize_io()
(see I/O Functions).in_stream
is read in character-by-character inmain()
, however this serves no useful purpose as yet.
Used for writing the file of MetaPost code, which is 3DLDF's output. Currently attached to the file subpersp.mp by
initialize_io()
(see I/O Functions).
TeX code can be written to a file through
tex_stream
, if desired. 3DLDF makes no use of it itself. Currently attached to subpersp.tex byinitialize_io()
(see I/O Functions).
