NAME

       mongoc_socket_sendv - mongoc_socket_sendv()

SYNOPSIS

          ssize_t
          mongoc_socket_sendv (mongoc_socket_t *sock,
                               mongoc_iovec_t *iov,
                               size_t iovcnt,
                               int64_t expire_at);

PARAMETERS

       • sock: A mongoc_socket_t.

       • iov: A mongoc_iovec_t.

       • iovcnt: A size_t containing the number of elements in iov.

       • expire_at:  A int64_t with absolute timeout in monotonic time. The monotonic clock is in
         microseconds and can be fetched using System Clock.

DESCRIPTION

       Sends a vector of buffers to the  destination.  This  uses  sendmsg()  when  available  to
       perform a gathered write. If IOV_MAX is reached, a fallback will be used.

RETURNS

       the number of bytes sent on success, or -1 on failure and errno is set.
