std::allocator<T>::max_size (3) - Linux Man Pages

std::allocator<T>::max_size: std::allocator<T>::max_size


std::allocator<T>::max_size - std::allocator<T>::max_size


size_type max_size() const throw(); (until C++11)
                                      (since C++11)
size_type max_size() const noexcept; (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).



Return value

The maximum supported allocation size
