C++ deque get_allocator用法及代码示例双端队列::get_allocator()是C++ STL中的内置函数,用于获取容器双端队列的分配器。 用法: Allocator_type get_allocator() 参数:该函数不接受任何参数。 返回值:返回与双端队列相关的分配器。 以下示例程序旨在说明deque::get_allocator()函数的工作。示例1: // CPP ...
In C++, allocators are used in the standard library to handle the allocation and deallocation of elements stored in containers. Allocation is a process of requesting access to a data set. If you allocate a data set that exists, the system allows you to open the data set, and if you allo...
CTransInPlaceInputPin.GetAllocator 方法 - GetAllocator 方法检索此引脚建议的内存分配器。 此方法实现 IMemInputPin::GetAllocator 方法。
CBaseInputPin.GetAllocator 方法 - GetAllocator 方法會擷取這個針腳所建議的記憶體配置器。 這個方法會實作 IMemInputPin::GetAllocator 方法。
CBaseInputPin::GetAllocatorThe GetAllocator method retrieves the memory allocator proposed by this pin. This method implements the IMemInputPin::GetAllocator method.SyntaxHRESULT GetAllocator( IMemAllocator **ppAllocator ); ParametersppAllocator
ppAllocator Pointer to an obtainedIMemAllocatorobject. Return Values Default implementation returns either E_OUTOFMEMORY, if an allocator cannot be created, or NOERROR upon success. Remarks This member function implements theIMemInputPin::GetAllocatormethod, which is called by the connected output pin...
