Requests that the host allocate the specified amount of memory from the heap.
[in] The size, in bytes, of the current memory allocation request.
[in] One of the EMemoryCriticalLevel values, indicating the impact of an allocation failure.
[out] A pointer to the allocated memory, or null if the request could not be completed.
Alloc returned successfully.
The common language runtime (CLR) has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully.
The call timed out.
The caller does not own the lock.
An event was canceled while a blocked thread or fiber was waiting on it.
An unknown catastrophic failure occurred. When a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.
Not enough memory was available to complete the allocation request.
The CLR gets an interface pointer to an IHostMalloc instance by calling the IHostMemoryManager::CreateMalloc method.
