IDebugExpressionEvaluator2::PreloadModules

  • Article

Preloads the modules designated by the specified symbol provider.

Syntax

int PreloadModules (
    IDebugSymbolProvider pSym
);

Parameters

pSym
[in] Symbol provider for which the modules will be preloaded.

Return Value

If successful, returns S_OK; otherwise, returns an error code.

Remarks

This optional method is used when you do a hosting-process attach. It gives the EE a chance to 'warm up' as part of the attach.

Example

The following example shows how to implement this method for an ExpressionEvaluatorPackage object that exposes the IDebugExpressionEvaluator2 interface.

STDMETHODIMP ExpressionEvaluatorPackage::PreloadModules
(
    IDebugSymbolProvider *pSym
)
{
    HRESULT hr = NOERROR;
    RuntimeMemberDescriptor  * prtMemberDesc;
    RuntimeClassDescriptor *prtClassDesc;
    CComPtr<IDebugClassField> pClassField;
    IfFalseGo(pSym,E_INVALIDARG);

    prtMemberDesc = &(g_rgRTLangMembers[StandardModuleAttributeCtor]);
    prtClassDesc = &(g_rgRTLangClasses[prtMemberDesc->rtParent]);
    pSym->GetClassTypeByName(prtClassDesc->wszClassName, nmCaseSensitive, &pClassField);

    pClassField = NULL;
    prtMemberDesc = &(g_rgRTLangMembers[LoadAssembly]);
    prtClassDesc = &(g_rgRTLangClasses[prtMemberDesc->rtParent]);
    pSym->GetClassTypeByName(prtClassDesc->wszClassName, nmCaseSensitive, &pClassField);

Error:
    return hr;
}
