size_type max_size()constnoexcept;		(since C++11) (deprecated in C++17) (removed in C++20)

Returns the maximum theoretically possible value of n, for which the call allocate(n, 0) could succeed.

In most implementations, this returns std::numeric_limits<size_type>::max()/ sizeof(value_type).

Parameters

(none)

Return value

The maximum supported allocation size.

See also

max_size [static]

returns the maximum object size supported by the allocator (public static member function of std::allocator_traits<Alloc>)
