/* For COM compatibility reasons, we want to use exact error code numbers
for NS_ERROR_PROXY_INVALID_IN_PARAMETER and NS_ERROR_PROXY_INVALID_OUT_PARAMETER.
The first matches:
#define RPC_E_INVALID_PARAMETER _HRESULT_TYPEDEF_(0x80010010L)
Errors returning this mean that the xpcom proxy code could not create a proxy for
one of the in paramaters.
Because of this, we are ignoring the convention if using a base and offset for
error numbers.

This is returned only when the "real" meathod has NOT been invoked.
