- .SH SYNOPSIS
- .B #include <u.h>
- .br
- .B #include <libc.h>
- .sp
- .B
- char* cleanname(char *filename)
- .SH DESCRIPTION
- .I Cleanname
- takes a
- .I 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
- .B .
- and
- .B ..
- directory components in the name.
- The string is overwritten in place.
- .PP
- The shortest string
- .I cleanname
- can return is two bytes: the null-terminated string
- \f(CW"."\f1.
- Therefore
- .I filename
- must contain room for at least two bytes.
