Equivalent C Types for Built-in SQL Types

https://www.postgresql.org/docs/15/xfunc-c.html#XFUNC-C-TYPE-TABLE

Does postgres have Equivalent  C range Type for Built-in SQL range Types?

No, there is only common ancestor - RangeType

Ranges are containers like arrays or records - so has not own type specific type

look https://github.com/postgres/postgres/blob/master/src/backend/utils/adt/rangetypes.c

technically, Can i use jsonbor range  or array in C-language function?

If that's possible, for range type  I need #include rangetypes.h in the c file(used to create c function) ?
