n = ftell(handle)
The handle argument must be a valid and active file handle. The
return is the offset into the file relative to the start of the
file (in bytes).
ftell to determine the current file
position. We read 512 4-byte floats, which results in the file
pointer being at position 512*4 = 2048.
