thanks a lot!!! re-read it again!!!

from the struct doc!
Standard size and alignment are as follows: no alignment is required
for any type (so you have to use pad bytes); short is 2 bytes; int and
long are 4 bytes; long long (__int64 on Windows) is 8 bytes; float and
double are 32-bit and 64-bit IEEE floating point numbers,
respectively.
