src/include/liburing.h:629–641

* io_uring_prep_splice() - Either @fd_in or @fd_out must be a pipe. * * - If @fd_in refers to a pipe, @off_in is ignored and must be set to -1. * * - If @fd_in does not refer to a pipe and @off_in is -1, then @nbytes are read * from @fd_in starting from the file offset, which is incremented by the * number of bytes read. * * - If @fd_in does not refer to a pipe and @off_in is not -1, t
