Discards excess capacity.
void shrink_to_fit(
);
Remarks
There is no portable way to determine if shrink_to_fit reduces the storage used by a deque Class.
Example
// deque_shrink_to_fit.cpp
// compile with: /EHsc
#include <deque>
#include <iostream>
int main( )
{
using namespace std;
deque <int> v1;
//deque <int>::iterator Iter;
v1.push_back( 1 );
v1.push_back( 2 );
cout << "Current size of v1 = "
<< v1.size( ) << endl;
v1.shrink_to_fit();
cout << "Current size of v1 = "
<< v1.size( ) << endl;
}
Current size of v1 = 1 Current size of v1 = 1
