Returns

the pointer to the target specific struct without matching a magic number. Use in target specific service routines, where the correct type of arch_info is certain.

Returns

the pointer to the target specific struct or NULL if the magic number does not match. Use in a flash driver or any place where mismatch of the arch_info type can happen.
