	Use stat(2) if you have a pathname for a file, or fstat(2) if you
have a file descriptor resulting from another system call which has already
opened the file.
	Both stat(2) and fstat(2) return a pointer to a stucture (found in
/usr/include/sys/stat.h), in which the variable st_ino is the inode number.
	The above applies to System V; but I can't speak for Beserkeley.
