Suggestion on publishing arrays

[hei-jung]

Hi,
I am trying to publish an array of doubles by converting it to const char array using memcpy.
The problem is that if I set the array size bigger and bigger, the subscriber will get wrong data: about first 100 values are sent correctly, but from the next becomes garbage data.
After struggling, I came to a conclusion that there is a problem setting a message buffer when I'm trying to publish data too large.
So I suggest, could you add ability to publish message with the message length something like this:

void publish(const char* subject, const char* msg, int msg_length);

I appreciate your work.
