[cs631apue] HW#2

[Rob Hoffmann]

Professor,

When I presented my code in class you mentioned that I should change my 
char buffer to a void buffer. If this is the case, is copying binary 
files a required part of the assignment, and if so should I be changing 
read/write to fread/fwrite in order to accommodate this?
