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 fileSYNOPSIS¶
int
splice_from_pipe_feed(struct pipe_inode_info * pipe,
struct splice_desc * sd,
splice_actor * actor);
ARGUMENTS¶
pipepipe 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.COPYRIGHT¶
