Re2 (rand() in C): A little C code converted to Perl *HELP*

[bbfu]

The rand function in C returns a random integer. The OP's C code seems to assume 16 bit integers, so that's a max of 65535 (or 32767 to -32768, IIRC). So, I think the equivalent Perl code would be something like:

$gcheck = sprintf "%x", ((int(rand(65536)) << 16) | int(rand(65536)));
