Re: [OT] C help plz..

[Shao Zhang <shao@cia.com.au>]

But isn't %[Xx] just prints out as Hexdecimal?
I just tried, and it prints out something like: 38c9616e

which consumes 8 bytes in a file. Given that unsigned long is 32 bits,
I want to use exactly 4 byte to represent it in order to save some
space.

Thanks.

Shao.
