[cs631apue] Midterm Question

[tparisi]

Then I am confused because st_blocks holds the number of blocks the 
file is allocated.  What size blocks would that be calculated for?  I 
ask because I only set the BLOCKSIZE to 512 in my program and then count 
the number of blocks the files use.  Then I use export BLOCKSIZE=512 and 
run ls -l and I get the same number for the total.  So I guess my 
question is, why do these numbers match if I have to use the BLOCKSIZE 
somehow in my ls program?
Thanks,
