My first post :-)
I need to read a file that has the following basic layout:
table-size - 32 bits
[ frequency - 32 bits
byte - 8 bits]+
message-size - 32 bits
message ...
Now, the problem I have is that I have never used scheme for programming
on this low level before -- I have never had to read a specific number
of bytes from a file and convert those bytes to an integer. I can't find
any information on how to do it, I guess SRFI-4 is related, but from the
webpage that the chicken manual refers to[1] I can't figure it out. I
also can't find any kind of read-byte, read-32bits, or similar function
in the manual.
I'd be glad for any pointers :-)

Advice is what we ask for when we already know the answer but wish we
didn't.
