boost::dynamic_bitset::reserve

Declared in <boost/dynamic_bitset/dynamic_bitset.hpp>

After reserve(), capacity() is greater or equal to the argument of reserve() if reallocation happens; and equal to the previous value of capacity() otherwise. Reallocation happens at this point if and only if the current capacity is less than the argument of reserve().

If AllocatorOrContainer is a container, it provides reserve().

It does not change the size of the bitset.

An allocation error if memory is exhausted (std::bad_alloc if allocator_type is a std::allocator). If the number of blocks needed exceeds the max_size() of the underlying container, whatever that container throws in that case (std::length_error for a std::vector).
