[Redis Module] How to get unsigned long from RedisModuleString?

[RinChanNOWWW]

There is only a method RedisModule_StringToLongLong to get integer from RedisModuleString. But the range of unsigned long and long long are different (18446744073709551615 and 9223372036854775807 on my machine), so we can't get unsigned long by RedisModule_StringToLongLong.

Is there any approach to get unsigned long directly from RedisModuleString or get the raw string?

The only way I come up with is a little hacky. IT IS: construct a struct totally same as robj (since we can't use robj when writing Redis Module, or we can?), and cast RedisModuleString to robj forcibly. Then we can get the raw string by robj.ptr.

Please tell me what is the best way to get unsigned long from RedisModuleString.
