Use BUFSIZ for the amount of data to copy through stdio.

Browse source 
According to the book of armaments(posix):
BUFSIZ
    Size of <stdio.h> buffers. This shall expand to a positive value.

There is also no need for the buflen variable since the size never
changes during runtime and the compiler can infer the size via
sizeof().
