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.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.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.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.Unix_error
on ERRNO.
