(deprecated in 哋它亢++17)

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.
