Retrieves the debug symbols with the given parent attribute for the specified module.

Syntax

HRESULT GetSymAttribute (
    ULONG32  ulAppDomainID,
    GUID     guidModule,
    _mdToken tokParent,
    LPOLESTR pstrName,
    ULONG32  cBuffer,
    ULONG32* pcBuffer,
    BYTE*    buffer
);

int GetSymAttribute (
    uint      ulAppDomainID,
    Guid      guidModule,
    int       tokParent,
    string    pstrName,
    uint      cBuffer,
    out uint  pcBuffer,
    out int[] buffer
);

Parameters

ulAppDomainID
[in] Identifier of the application domain.

guidModule
[in] Unique identifier of the module.

tokParent
[in] Token for the parent attribute.

pstrName
[in] Name of the module.

cBuffer
[in] Number of bytes required for the output buffer.

pcBuffer
[out] Length of the output buffer.

buffer
[out] Array that contains the symbols.

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::GetSymAttribute(
    ULONG32 ulAppDomainID,
    GUID guidModule,
    _mdToken tokParent,
    __in_z LPOLESTR pstrName,
    ULONG32 cBuffer,
    ULONG32 *pcBuffer,
    BYTE buffer[])
{
    HRESULT hr = S_OK;
    CComPtr<CModule> pModule;
    Module_ID idModule(ulAppDomainID, guidModule);

    METHOD_ENTRY( CDebugSymbolProvider::GetSymAttribute );

    IfFailGo( GetModule( idModule, &pModule) );

    IfFailGo( pModule->GetSymAttribute( tokParent, pstrName, cBuffer, pcBuffer, buffer ) );

Error:

    METHOD_EXIT(CDebugSymbolProvider::GetSymAttribute, hr);

    return hr;
}
