вот так 

#pragma pack(1)

typedef struct{

	unsigned char   bVar;

	unsigned short  wVar;

}t_3byte;

#pragma pack()

unsigned char   rgVar[20]={1,2,3,4,5,6,7,8,9,0};

void main(){

unsigned char   bVar, i;

unsigned short  wVar;

  i=1;

  bVar =  ((t_3byte*)(rgVar+sizeof(t_3byte)*i))->bVar;

  wVar =  ((t_3byte*)(rgVar+sizeof(t_3byte)*i))->wVar;

  i++;

  bVar =  ((t_3byte*)(rgVar+sizeof(t_3byte)*i))->bVar;

  wVar =  ((t_3byte*)(rgVar+sizeof(t_3byte)*i))->wVar;

}
