úÎ,+p    Safe-InferedThe numeric type used by % for chunk size recommendations when  moving data. GMoves data between two file descriptors without copying between kernel < address space and user address space. It transfers up to len bytes of ! data from the file descriptor fd_in to the file descriptor fd_out, 6 where one of the descriptors must refer to a pipe.  is NOT+ a loop and needs to be called repeatedly. For an example, see . EAttempt to move pages instead of copying. This is only a hint to the % kernel: pages may stil be copied (in kernel address space) if the kernel B cannot move the pages from the pipe, or if the pipe buffers don' t refer to  full pages. )More data will be coming in a subsequent . This is a helpful hint  when fd_out refers to a socket. Do not block on I/O. This makes the  pipe operations  nonblocking, but ) may nevertheless block because the file  descriptors that are d to/%from may block (unless they have the   O_NONBLOCK flag set). fd_in. off_in. fd_out. off_out. len. flags. 3number of bytes moved if successful; otherwise -1.
