IHostMemoryManager::CreateMAlloc Method

  • Article

Gets an interface pointer to an IHostMAlloc instance that is used to make allocation requests from a heap created by the host.

Syntax

HRESULT CreateMalloc (  
    [in]  DWORD         dwMallocType,  
    [out] IHostMalloc **ppMalloc  
);

Parameters

dwMallocType
[in] A combination of MALLOC_TYPE flags that specifies the characteristics of the memory that is being allocated.

ppMAlloc
[out] A pointer to the address of an IHostMAlloc instance provided by the host.

Return Value

HRESULT Description
S_OK CreateMAlloc returned successfully.
HOST_E_CLRNOTAVAILABLE 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.
HOST_E_TIMEOUT The call timed out.
HOST_E_NOT_OWNER The caller does not own the lock.
HOST_E_ABANDONED An event was canceled while a blocked thread or fiber was waiting on it.
E_FAIL 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.
E_OUTOFMEMORY Not enough physical memory was available to complete the allocation request.

Remarks

CreateMAlloc returns an object that allows the CLR to make allocation requests through the host instead of using the standard Win32 functions.
