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. |
