IHostMAlloc::DebugAlloc Method
Requests that the host allocate the specified amount of memory from the heap, and additionally track where the memory was allocated.
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.
