I can't find a library listing of INMODs or UDFs anywhere on here.
I'm sure someone has written some of these to parse out binary data into CHARacter strings. How do I find them?
what exactly are you trying to do?
Maybe the FROM_BYTES function is what you need:
select from_bytes('1234567890abcdef'xb, 'base16')
I'm trying to get a better definition, but they're trying to unpack some redefined record formats and use bit math to get masks of some form or another, and there will be different redefines/data format over time.
