IN THIS PACKAGE
Module Lwt_cstruct
val read : Lwt_unix.file_descr -> Cstruct.t -> int Lwt.t

read fd t reads data from the file descriptor fd into the t cstruct.

  • returns

    the numbers of bytes actually read.

val write : Lwt_unix.file_descr -> Cstruct.t -> int Lwt.t

write fd t writes data from the t cstruct to the file descriptor fd.

  • returns

    the numbers of bytes actually written.

val complete : ( Cstruct.t -> int Lwt.t ) -> Cstruct.t -> unit Lwt.t

complete (read fd) t fills t with data from fd.

complete (write fd) t fully-writes t to fd.

  • raises End_of_file

    if the file descriptor operation fails.

sendto fd t flags sa invokes Lwt_unix.sendto on the t cstruct.

  • returns

    the number of bytes sent.

val recvfrom : Lwt_unix.file_descr -> Cstruct.t -> Unix.msg_flag list -> (int * Unix.sockaddr) Lwt.t

recvfrom fd t flags sa invokes Lwt_unix.recvfrom on the t cstruct.

  • returns

    the number of bytes read and the socket address of the remote side.
