Name:seq_buf_to_user - copy the squence buffer to user space*@s: seq_buf descriptor*@ubuf: The userspace memory location to copy to*@cnt: The amount to copy* Copies the sequence buffer into the userspace memory pointed to* by @ubuf

Proto:int seq_buf_to_user(struct seq_buf *s, char __user *ubuf, int cnt)

Type:int

Parameter:

Type	Parameter	Name
struct seq_buf *	s
char __user *	ubuf
int	cnt

If Not cnt Then Return 0

314

len = How much buffer was written?

316

If len <= readpos Then Return -EBUSY

319

len -= readpos

320

If cnt > len Then cnt = len

322

ret = copy_to_user(ubuf, buffer + readpos, cnt)

323

If ret == cnt Then Return -EFAULT

326

cnt -= ret

328

readpos += cnt

329

Return cnt
