SPLICE_FROM_PIPE_FEE(9)                     splice API                    SPLICE_FROM_PIPE_FEE(9)



NAME
       splice_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.
