cleanname(3) - Plan 9 from User Space

| CLEANNAME(3) | CLEANNAME(3)
| 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.
