CCS: Memory address of structure members

Hi,

One doubt about the memory address of structure members.

Are the members' address in sequence as their definition sequence? Customer wants to get access to structure members by structure start address. If their memory address follows the definition sequence, customer can do.

Thanks a lot.

Br, Jordan

    Yes.  The C standard requires it.

    Consider using the macro offsetof in the C standard header file stddef.h.  I recommend you read about it in your favorite book or web site on C.

    Thanks and regards,
