Defined in header <memory>
static size_type max_size( const Alloc& a ) noexcept;		(since C++11)

If possible, obtains the maximum theoretically possible allocation size from the allocator a, by calling

a.max_size()

If the above is not possible (e.g. a does not have the member function max_size()), then returns std::numeric_limits<size_type>::max() (until C++17)std::numeric_limits<size_type>::max() / sizeof(value_type) (since C++17)

Parameters

(none)

Return value

Theoretical maximum allocation size

See also

max_size (deprecated in C++17)(removed in C++20)

returns the largest supported allocation size (public member function of std::allocator<T>)
