iov A vector of mongoc_iovec_t \&.
iovcnt The number of items in iov \&.
timeout_msec
The number of milliseconds to block before indicating failure, or 0 for non‐blocking. Negative
values indicate the default timeout.
The mongoc_stream_writev(3) function shall perform a write to a mongoc_stream_t \&. It's modeled on the
