Subject: [Boost-users] [array] with variable size
From: Hicham Mouline (hicham_at_[hidden])

I have a third-party library that gives me a number N of doubles,
then expects from me a double* to an array where it will set N elements

This would have happen many times and N is variable,
so I wish not to reallocate the array each time.

I know however N is maxed at some value Nmax like 50.

I thought of using a array<double, Nmax> that would be allocated once,
then perhaps have a wrapper around it so that only N elements of it
can be accessed.

This seems to be a usual idiom, are there ready implementations?
