示例1: TestAllocator
void TestAllocator(Allocator& a) {
EXPECT_TRUE(a.Malloc(0) == 0);
uint8_t* p = (uint8_t*)a.Malloc(100);
EXPECT_TRUE(p != 0);
for (size_t i = 0; i < 100; i++)
p[i] = (uint8_t)i;
// Expand
uint8_t* q = (uint8_t*)a.Realloc(p, 100, 200);
EXPECT_TRUE(q != 0);
for (size_t i = 0; i < 100; i++)
EXPECT_EQ(i, q[i]);
for (size_t i = 100; i < 200; i++)
q[i] = (uint8_t)i;
// Shrink
uint8_t *r = (uint8_t*)a.Realloc(q, 200, 150);
EXPECT_TRUE(r != 0);
for (size_t i = 0; i < 150; i++)
EXPECT_EQ(i, r[i]);
Allocator::Free(r);
// Realloc to zero size
EXPECT_TRUE(a.Realloc(a.Malloc(1), 1, 0) == 0);

int a = 64;
while( a < l )
a = a * 2;
data = (char *) al.Realloc(data, a);
