CLEANNAME(2)							  CLEANNAME(2)

NAME
       cleanname - clean a path name

SYNOPSIS
       #include <u.h>
       #include <libc.h>

       char*	 cleanname(char *filename)

DESCRIPTION
       Cleanname  takes	 a filename and by lexical processing only returns the
       shortest string that names the same (possibly hypothetical)  file.   It
       eliminates multiple and trailing slashes, and it lexically interprets .
       and ..  directory components in the name.  The string is overwritten in
       place.

       The  shortest string cleanname can return is two bytes: the null-termiā€
       nated string ".".  Therefore filename must contain room	for  at	 least
       two bytes.
