const char *test = "this is a test \n";
MemReadStream ms(test, strlen(test));
Cout().Put(ms); //cheap...
(De)serialization, which eventually involves copying if you're going to put the data into new String, can be done via Stream helpers.(Eg LoadStream, SaveStream et al.)
Best regards,

Cool that works. ms.Put(Cout()) did not work.

If it was just for display I'd be fine with copying, but suppose you wanted to perform a text search within the fields of a million mmaped records. It's a lot of unnecessary copying.
