IHostMAlloc::DebugAlloc Method
Requests that the host allocate the specified amount of memory from the heap, and additionally track where the memory was allocated.
Syntax
HRESULT DebugAlloc (
[in] SIZE_T cbSize,
[in] EMemoryCriticalLevel dwCriticalLevel,
[in] char* pszFileName,
[in] int iLineNo,
[out] void** ppMem
);
Parameters
cbSize
[in] The size, in bytes, of the current memory allocation request.
dwCriticalLevel
[in] One of the EMemoryCriticalLevel values, indicating the impact of an allocation failure.
pszFileName
[in] The code file of the executable being debugged.
iLineNo
[in] The line number in pszFileName where the allocation was requested.
ppMem
[out] A pointer to the allocated memory, or null if the request could not be completed.
Return Value
| HRESULT | Description |
|---|---|
| S_OK | DebugAlloc returned successfully. |
| HOST_E_CLRNOTAVAILABLE | The 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 memory was available to complete the allocation request. |
Remarks
The CLR gets an interface pointer to an IHostMalloc instance by calling the IHostMemoryManager::CreateMalloc method. DebugAlloc allows the runtime to get code file information for use during debugging.
