Some people keep repeating that the fseek function could not work 
because some obscure machines do not support byte offsets.

When pressed with the request of an example, they almost always go to 
the IBM mainframe world.

Note:

IBM C supports fseek using bytes offsets. Only in files with variable 
length records, you have to supply the byteseek option to fopen and it 
will be ALSO be able to use byte offsets.

This example also doesn't work. I would say that for all practical 
purposes the method of calculating the length of a file using the fseek 
function should work.
