Sendmsg

For detailed semantics of these functions, consult the sendmsg (3) and recvmsg (3) man pages.

val send : Unix.file_descr -> ?fd:Unix.file_descr -> bytes -> int -> int -> int

send sock ?fd buf off n sends up to n bytes of buf, starting from off, over sock. fs is attached as ancillary data. Returns the number of bytes sent.

raises Unix_error
on ERRNO.

val recv : 
  Unix.file_descr ->
  bytes ->
  int ->
  int ->
  int * Unix.file_descr option

recv sock ?fd off n reads up to n bytes into buf, starting from off, from sock. Returns (n, fd), where n is the number of bytes read, and fd is the optional file descriptor attached to the message.

raises Unix_error
on ERRNO.

val sendv : Unix.file_descr -> ?fd:Unix.file_descr -> bytes array -> int

sendv sock ?fd bytesv is the scatter-gather version of send. It sends the contents of all bytes in bytesv, in order. Returns the number of bytes sent.

raises Unix_error
on ERRNO.

val recvv : Unix.file_descr -> bytes array -> int * Unix.file_descr option

recvv sock bytesv is the scatter-gather version of recv. Input is gathered into the arrays in bytesv, in order. Returns the total number of bytes read, and an optional file descriptor.

raises Unix_error
on ERRNO.
