Re: [boost] How to get the size of an C-array?

Sid Sacek a écrit :

I'm going to take a guess. Of course, this is all contingent on whether T is a class that contains a destructor, otherwise all bets are off. -Sid Sacek

[...] T * tp = new T[ 100 ];

size_t array_size = reinterpret_cast< size_t * >( tp )[ -1 ];

I think this is not going to work if T has a stricter alignment than size_t.
