示例1: test_Buffer
static int test_Buffer (){
cout << "Go Testing" << __FILE__ << endl;
MemoryPool pool;
Buffer buffer( &pool, 10);
buffer.copy ( "hellohelloX", 11); // too big, will not copy
cout << (char*)buffer.data () << "," << buffer.size () << "," << buffer.capacity () << endl;
buffer.copy ( "world", 5);
cout << (char*)buffer.data () << "," << buffer.size () << "," << buffer.capacity () << endl;
Buffer otherBuffer (buffer);
cout << (char*)otherBuffer.data () << "," << otherBuffer.size () << "," << otherBuffer.capacity () << endl;
pool.clear ();
cout << "test RingBuffer" << endl;
RingBuffer ringBuffer( &pool, 3);
int rs = 0;
rs = ringBuffer.copy ("hel", 3);
DLog("copied:", rs, (char*)ringBuffer.data () );
rs = ringBuffer.copy ("worldp", 6);
DLog("copied:", rs, (char*)ringBuffer.data ());
rs = ringBuffer.copy ("worldpq", 7);
DLog("copied:", rs, (char*)ringBuffer.data ());
cout << "capacity:" << ringBuffer.capacity () << "=>" << (char*)ringBuffer.data () << endl;
return 0;
}示例2: test_MemoryPool
static int test_MemoryPool (){
cout << "Go Testing" << __FILE__ << endl;
MemoryPool pool;
auto ptr1 = pool.alloc (5);
auto ptr2 = pool.alloc (10);
auto ptr3 = pool.alloc (11);
pool.dump ();
pool.free (ptr1);
pool.free (ptr2);
pool.dump ();
int* ptr4 = (int*)ptr3;
// ptr4++; // error !!
pool.free ( (void*&)ptr4 );
// clear
cout << "clear" << endl;
pool.dump ();
pool.clear ();
pool.dump ();
cout << "clear done." << endl;
// for c++
A* a = pool.cnew<A>();
pool.dump ();
pool.cdelete<A>(a);
pool.dump ();
cout << "a=>" << a << endl;
return 0;
