Both :-)
- get some sort of status indication that a memory read was invalid
- not have the error message printed
my code looks like:
uint8_t byte;
//printf("%zx/%zu", addr, addr);
db_read_bytes(addr, sizeof(byte), &byte);
//printf(" %02x/%u\n", byte, byte);
lua_pushinteger(L, byte);
return 1;
if the address is invalid, something inside of db_read_bytes prints a
message but still returns. Not exactly correct :-)

Ah, I'll dig further :-)
