[cs631apue] About FTS

[Yuxi Wang]

Hi professor,

Here is the quote from fts(3):

1.To use these fields to reference any files represented by
other FTSENT structures will require that the path buffer be modified
using the information contained in that FTSENT structure's fts_pathlen
field.  Any such modifications should be undone before further calls to
fts_read() are attempted.  The fts_name field is always NUL-terminated.

I saw the source code of fts.c. I can understand a single buffer is used for all of the paths of all of the files in the file hierarchy. But I don’t know how to only use fts_path to reference files. What the manual want to tell us? Could you give me a example or something?

2.What does the fts_accpath represent for? I tracked the FTS structure and found it always equal fts_name.

Thank you.
