If we're going to return int32_t, this should probably be PP_ERROR_BADRESOURCE.
I would actually change the return value of this function to be PP_Bool and just
return  PP_FALSE here, but I'll leave this up to you.

Just to distinguish between cases when method was called with incorrect
name/value/value type arguments and when some internal error occurs I prefer to
return int32_t.
