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.
