NAME

6       splice_from_pipe_feed - feed available data from a pipe to a file
7

SYNOPSIS

9       int splice_from_pipe_feed(struct pipe_inode_info * pipe,
10                                 struct splice_desc * sd,
11                                 splice_actor * actor);
12

ARGUMENTS

14       pipe
15           pipe to splice from
16
17       sd
18           information to actor
19
20       actor
21           handler that splices the data
22

DESCRIPTION

24       This function loops over the pipe and calls actor to do the actual
25       moving of a single struct pipe_buffer to the desired destination. It
26       returns when there's no more buffers left in the pipe or if the
27       requested number of bytes (sd->total_len) have been copied. It returns
28       a positive number (one) if the pipe needs to be filled with more data,
29       zero if the required number of bytes have been copied and -errno on
30       error.
31
32       This, together with splice_from_pipe_{begin,end,next}, may be used to
33       implement the functionality of __splice_from_pipe when locking is
34       required around copying the pipe buffers to the destination.
