std::allocator_traits<Alloc>::max_size: std::allocator_traits<Alloc>::max_size

NAME

std::allocator_traits<Alloc>::max_size - std::allocator_traits<Alloc>::max_size

Synopsis

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
