HRESULT GetHelpInfo ( HRESULT hrError, DWORD dwLookupID, LCID lcid, BSTR * pbstrHelpFile, DWORD * pdwHelpContext);
Parameters
- hrError
- [in]
The code returned by the method that caused the error. - dwLookupID
- [in]
The provider-specific number of the error. - lcid
- [in]
The locale ID for which to return the Help file path and context ID. - pbstrHelpFile
- [out]
A pointer to memory in which to return a pointer to a string containing the fully qualified path of the Help file. If there is no Help file or an error occurs, the returned value (*pbstrHelpFile) is a null pointer. The memory for this string is allocated by the provider and must be freed by the consumer with a call to SysFreeString. - pdwHelpContext
