Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

Create a new modifiable buffer that represents the given POD array.

template<
    typename PodType,
    std::size_t N>
mutable_buffer buffer(
    PodType (&data)[N],
    std::size_t max_size_in_bytes);

A mutable_buffer value equivalent to:

mutable_buffer(
    static_cast<void*>(data),
    min(N * sizeof(PodType), max_size_in_bytes));
