Re: __align in c++

It means if i declare
__align(128) unsigned char buffer[10];

then suppose address of buffer[0]=a
buffer[1]=a+128/8;

Re: __align in c++

But i have seen that
__align(16) unsigned char buffer[20];

what will be its benefit here for declaring buffer of 20 elements which can store only value from 0 to 255?

__align in c++

Hi,
I have read that __align is used to set the boundary of variable, what is its benefit.
suppose __align(2) unsigned short u;

even unsigned short variable can have its value from 0 to 65535. then where is difference lies.
second thing, can we say that __align is a qualifier in c/c++.
Thanks.
