Placing a structure member in particular memory segment

Hi,

I wanted to allocate a particular structure member in my choice of memory, so i declared the structure as followed,

struct xyz

{

#pragma DATA_SECTION( x, ".sbsram")

int x[10000];

int y[10000];

int z[10000];

};

When i compile i get the error

#837-D pragma can only be applied to a file level symbol, not 'x,',

How to rectify it, and place a stucture member in the particular segment of memory.

Regards,

Deepa

You cannot use #pragma DATA_SECTION on a type declaration. You can only use it on a variable declaration, such as:

#pragma DATA_SECTION(thing, ".sbsram")
struct xyz thing;

Also, it makes no sense to try to allocate a member of an aggregate to a section different from the rest of the aggregate.

Maybe what he wants to accomplish could be done by making the structure members pointers to arrays rather than arrays (along with other necessary adjustments).
