It transfers up to len bytes of data from the file descriptor fd_in to the file descriptor fd_out , where one of the descriptors must refer to a pipe. If fd_in refers to a pipe, then off_in must be NULL. If fd_in does not refer to a pipe and off_in is NULL, then bytes are read from fd_in starting from the current file offset, and the current file offset is adjusted appropriately. If fd_in does not refer to a pipe and off_in is not NULL, then off_in must point to a buffer which specifies the start...
