Subject: Extracting ints from a unsigned long

I have a bunch of binary data consisting of 4 ints stored inside an unsigned
long.

Here's psuedo C code to extract out the ints:

// data is a FILE pointer to the file
unsigned long temp;
fread(temp, sizeof(temp), 1, data);
int first = temp >> 24;
int second = temp << 8 >> 24;
int third = temp << 16 >> 24;
int fourth = temp << 24 >> 24;


I'm trying to do the same thing in Ruby, but I'm having difficulties with
the bitshifting.  Any ideas?  Would it make since to inline C code in Ruby
for this?
