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 bson_get_monotonic_time(3)
