Изобретаю очередной велосипед - создаю несложный GUI (ARM GCC)

Возник такой вопрос

Есть массив структур типа :typedef struct {
unsigned short widget;
unsigned short x;
unsigned short y;
unsigned short width;
unsigned short height;
unsigned char name[12];
unsigned short font;
unsigned short color;
unsigned short color_text;
unsigned short color_inact;
unsigned short color_alert;
unsigned short id;
unsigned short viz;
unsigned short click;
unsigned short group;
unsigned short child;
unsigned short value;
unsigned short attr1;
unsigned short attr2;

} gui_str ;
..............
gui_str gui[128];

Как обратиться к элементу name[12] из функции
void CreateButton(unsigned short x,unsigned short y,unsigned char*str)
