Iobuf has analogs of various Bigstring functions. These analogs advance by the amount written/read.

val read_assume_fd_is_nonblocking : ([> Core.write ], Iobuf.seek) Iobuf.t -> Core.Unix.File_descr.t -> Core.Unix.Syscall_result.Unit.t
val pread_assume_fd_is_nonblocking : ([> Core.write ], Iobuf.seek) Iobuf.t -> Core.Unix.File_descr.t -> offset:int -> unit
val recvfrom_assume_fd_is_nonblocking : ([> Core.write ], Iobuf.seek) Iobuf.t -> Core.Unix.File_descr.t -> Core.Unix.sockaddr
module Recvmmsg_context : sig ... end

recvmmsg's context comprises data needed by the system call. Setup can be expensive, particularly for many buffers.

recvmmsg_assume_fd_is_nonblocking fd context returns the number of context iobufs read into (or errno). fd must not block. THREAD_IO_CUTOFF is ignored.

EINVAL is returned if an Iobuf passed to Recvmmsg_context.create has its buf or limits changed.

val send_nonblocking_no_sigpipe : unit -> (([> Core.read ], Iobuf.seek) Iobuf.t -> Core.Unix.File_descr.t -> Core.Unix.Syscall_result.Unit.t) Core.Or_error.t

val write_assume_fd_is_nonblocking : ([> Core.read ], Iobuf.seek) Iobuf.t -> Core.Unix.File_descr.t -> unit
val pwrite_assume_fd_is_nonblocking : ([> Core.read ], Iobuf.seek) Iobuf.t -> Core.Unix.File_descr.t -> offset:int -> unit

module Expert : sig ... end

The Expert module is for building efficient out-of-module Iobuf abstractions.
