Corinna Vinschen> Yes, sure. Yes, you should use realpath(), but passing it NULL won't necessarily work. The second argument is supposed to be a pointer to the buffer in which it should put its result, and according to POSIX the call should fail if that argument is NULL. GNU has extended its version of realpath() to dynamically allocate a result buffer when the second argument is NULL. I would not assume that Cygwin does likewise, since it's a libc function and Cygwin doesn't use GNU libc. The safest course would be to declare or preallocate a buffer of size PATH_MAX and pass it to realpath(); that should work with any POSIX-compliant C library. -- Mark J.
