[C++-sig] Creating an arbitrary sized boost string ?

[John Janecek]

I can create a string using

str(char* data)
where data is a null terminated string

what about if data is not a null terminated string ?

like i need something like
str(unsigned char* data, datalen)

how can i do this ?

Thanx, it is probably in the docs but i can not find it :(
so please do not flame me too bad :)
