hash_map::max_size
Returns the maximum length of the hash_map.
size_type max_size( ) const;
Return Value
The maximum possible length of the hash_map.
Remarks
In Visual C++ .NET 2003, members of the <hash_map> and <hash_set> header files are no longer in the std namespace, but rather have been moved into the stdext namespace. See The stdext Namespace for more information.
Example
// hash_map_max_size.cpp
// compile with: /EHsc
#define _DEFINE_DEPRECATED_HASH_CLASSES 0
#include <hash_map>
#include <iostream>
int main( )
{
using namespace std;
using namespace stdext;
hash_map <int, int> hm1;
hash_map <int, int> :: size_type i;
i = hm1.max_size( );
cout << "The maximum possible length "
<< "of the hash_map is " << i << "."
<< endl << "(Magnitude is machine specific.)";
}
Sample Output
The following output is for x86.
The maximum possible length of the hash_map is 536870911.
(Magnitude is machine specific.)
