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.
