The filename structure is used to represent a tcc input or output

file. It has an associated name (the full pathname), a basename
|
|
|
40 |
(with the directory and file suffix removed), a file type (see
|
|
|
41 |
below) and a file storage type (see below). filenames are formed
|
|
|
42 |
into lists using the next field. The may also be associated into
|
|
|
43 |
groups which are passed around as if they were a single file using
|
|
|
44 |
the aux field.
