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-terminated string ".".  Therefore ­filename must contain room for at least two bytes.
