Hi Progga,
Thanks for the reply. Yes, __attribute__(packed) can be used but that
comes with processing overhead. I read some where on net (I am not very sure
about that), all compilers do not support such construct.
Regards,
Amit Dang

In that case use __attribute__ ((packed)) after the structure definition.
There'll be no alignment then and the size will always be the same.
struct hihi{
int a ;
char b ;
} __attribute__ ((packed)) ;
