SPLICE_FROM_PIPE_FEE(9) splice API SPLICE_FROM_PIPE_FEE(9)NAMEsplice_from_pipe_feed - feed available data from a pipe to a file
SYNOPSIS
int splice_from_pipe_feed(struct pipe_inode_info * pipe,
struct splice_desc * sd,
splice_actor * actor);
ARGUMENTS
pipe
pipe to splice from
sd
information to actor
actor
handler that splices the data
DESCRIPTION
This function loops over the pipe and calls actor to do the actual
moving of a single struct pipe_buffer to the desired destination. It
returns when there's no more buffers left in the pipe or if the
requested number of bytes (sd->total_len) have been copied. It returns
a positive number (one) if the pipe needs to be filled with more data,
zero if the required number of bytes have been copied and -errno on
error.
This, together with splice_from_pipe_{begin,end,next}, may be used to
implement the functionality of __splice_from_pipe when locking is
required around copying the pipe buffers to the destination.
