integer value for option 'CFG_INT' is out of range

[mik1234mc]

Hi all,

encountered weird behavior for parameter defined as CFG_INT. If I set to a value =>0x80000000 on 32bit system. Libconfuse (3.3) gives me conf.conf:17: integer value for option 'parameter' is out of range. What I am doing wrong that integer value is not valid?

Thanks,
Mike

CFG_INT is a signed integer. On a 32-bit system that means the maximum value is 0x7fffffff (2147483647).

See #11 for more information.

thank you for your answer. So, it turns out to be hex radix error; if I set -2147483648, it gives me 0x80000000. 0x80000000 is valid signed 32bit integer.

Yeah, we use strtol() to convert the input value. The syntax 0nnnnn, 0xnnnn, 0bnnnn, or nnnn is only syntactic sugar to establish the radix argument to that function. when you input 0x80000000 try to convert a postive hexadecimal value that is greater than the datatype can store. The value 0x7fffffff is the largest positive value you can store.
