SYNOPSIS¶
ssize_t mongoc_socket_sendv (mongoc_socket_t *sock,
mongoc_iovec_t *iov,

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 <https://www.mongoc.org/libbson/current/bson_get_monotonic_time.html>.
