mongoc_socket_send (mongoc_socket_t *sock,
                    const void *buf,
                    size_t buflen,
                    int64_t expire_at);

• sock: A mongoc_socket_t <>.
• buf: A buffer to send.
• buflen: A size_t with the number of bytes in buf.
• expire_at: A int64_t with an absolute timeout for the operation or 0. The timeout is in monotonic time using microseconds. You can retrieve the current monotonic time with System Clock <https://www.mongoc.org/libbson/current/bson_get_monotonic_time.html>.

Sends buflen bytes in buf to the destination. If a timeout expired, the number of bytes sent will be returned or -1 if no bytes were sent.

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