IHostMAlloc::DebugAlloc Method

  • Article

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.
  • 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 Interface instance by calling the IHostMemoryManager::CreateMAlloc Method method. DebugAlloc allows the runtime to get code file information for use during debugging.
