C++ (Cpp) DefaultDeallocator Examples

Example #1

File: SmallObj.cpp Project: wangscript/evolution3d

void SmallObjAllocator::Deallocate( void * p )
{
    if ( NULL == p ) return;
    assert( NULL != pool_ );
    FixedAllocator * pAllocator = NULL;
    const std::size_t allocCount = GetOffset( GetMaxObjectSize(), GetAlignment() );
    Chunk * chunk = NULL;

    for ( std::size_t ii = 0; ii < allocCount; ++ii )
    {

    }
    if ( NULL == pAllocator )
    {

    assert( NULL != chunk );
    const bool found = pAllocator->Deallocate( p, chunk );
