I think you may be looking for PersonalData from "nds\system.h" it is a pointer to a PERSONAL_DATA struct. so I think you should use it in place of USERDATA which does not appear to be initialized - at least in the code you provided.

error codes are usually helpfull in these situations - or more complete source code.

the error:
the unuusable variables: I know i will use then

quit wasting your time and post your source code. i think you havent #included the file elhobbs mentioned.

tPERSONAL_DATA is a struct name not a type. so you would need to use:

Code: Select all

struct tPERSONAL_DATA *USERDATA;

PERSONAL_DATA is a type definition for struct tPERSONAL_DATA. so you could use it like this:

Code: Select all

PERSONAL_DATA *USERDATA;

or you could use the already defined "PersonalData" which is declared at a fixed harware address.
