No it's not:
struct stat {
dev_t st_dev; /* inode's device */
...
off_t st_size; /* file size, in bytes */
off_t is 64 bits under FreeBSD.
A bunch of other unix systems have alternate system calls to get
64bit attributes for files.

Ok, who wrote this damn function called '??'?
And why do my programs keep crashing in it?
