do_splice_to

Name:Attempt to initiate a splice from a file to a pipe.

Proto:static long do_splice_to(struct file *in, loff_t *ppos, struct pipe_inode_info *pipe, size_t len, unsigned int flags)

Type:long

Parameter:

Type	Parameter	Name
struct file *	in
loff_t *	ppos
struct pipe_inode_info *	pipe
size_t	len
unsigned int	flags

873

ssize_t( * splice_read)(struct file * , loff_t * , struct pipe_inode_info * , size_t, unsigned int)

877

If Value for the false possibility is greater at compile time(!(f_mode & le is open for reading )) Then Return -EBADF

880

ret = rw_verify_area(generic data direction definitions , in, ppos, len)

881

If Value for the false possibility is greater at compile time(ret < 0) Then Return ret

884

If Value for the false possibility is greater at compile time(len > MAX_RW_COUNT) Then len = MAX_RW_COUNT

887

If splice_read Then splice_read = splice_read

889

Else splice_read = default_file_splice_read

892

Return splice_read(in, ppos, pipe, len, flags)
