Type:ssize_t

Parameter:

Type	Parameter	Name
struct file *	filp
const char __user *	buf
size_t	len
loff_t *	ppos

struct iovec iov = { BSD uses caddr_t (1003.1g requires void *) = (void __user * )buf, Must be size_t (1003.1g) = len}

479

init_sync_kiocb( & kiocb, filp)

480

The 'ki_filp' pointer is shared in a union for aio = If ppos Then ppos Else 0

481

iov_iter_init( & iter, WRITE, & iov, 1, len)

483

ret = call_write_iter(filp, & kiocb, & iter)

484

BUG_ON(ret == - cb queued, will get completion event )

485

If ret > 0 && ppos Then ppos = The 'ki_filp' pointer is shared in a union for aio

487

Return ret
