IDebugComPlusSymbolProvider::GetArrayTypeFromAddress
Retrieves type information about the specified array given its debug address.
[C++]
HRESULT GetArrayTypeFromAddress(
IDebugAddress* pAddress,
BYTE* pSig,
DWORD dwSigLength,
IDebugField** ppField
);
[C#]
int GetArrayTypeFromAddress(
IDebugAddress pAddress,
int[] pSig,
uint dwSigLength,
out IDebugField ppField
);
Parameters
pAddress
[in] The debug address represented by an IDebugAddress interface.pSig
[in] The array to examine.dwSigLength
[in] Length in bytes of the pSig array.ppField
[out] Returns the array type as represented by an IDebugClassField interface.
Return Value
If successful, returns S_OK; otherwise, returns an error code.
Example
The following example shows how to implement this method for a CDebugSymbolProvider object that exposes the IDebugComPlusSymbolProvider interface.
HRESULT CDebugSymbolProvider::GetArrayTypeFromAddress(
IDebugAddress *pAddress,
BYTE *pSig,
DWORD dwSigLength,
IDebugField **ppField)
{
HRESULT hr = E_FAIL;
CDEBUG_ADDRESS da;
CDebugGenericParamScope* pGenScope = NULL;
METHOD_ENTRY( CDebugDynamicFieldSymbol::GetArrayTypeFromAddress );
ASSERT(IsValidObjectPtr(this, CDebugSymbolProvider));
ASSERT(IsValidWritePtr(ppField, IDebugField*));
IfFailGo( pAddress->GetAddress(&da) );
if ( S_OK == hr )
{
IfNullGo( pGenScope = new CDebugGenericParamScope(da.GetModule(), da.tokClass, da.GetMethod()), E_OUTOFMEMORY );
IfFailGo( this->CreateType((const COR_SIGNATURE*)(pSig), dwSigLength, da.GetModule(), mdMethodDefNil, pGenScope, ppField) );
}
Error:
METHOD_EXIT( CDebugDynamicFieldSymbol::GetArrayTypeFromAddress, hr );
RELEASE( pGenScope );
return hr;
}
