我是 C 编码的新手,我遇到了以下结构中的“:”

struct __tag131
{ /* Bit Access */
unsigned char P0P6:1; /* P0P6 */
unsigned char P1P6:1; /* P1P6 */
unsigned char P2P6:1; /* P2P6 */
unsigned char P3P6:1; /* P3P6 */
unsigned char :2; /* Reserved Bits */
unsigned char TBP6:1; /* TBP6 */
unsigned char MKP6:1; /* MKP6 */
unsigned char :4; /* Reserved Bits */
unsigned char RFP6:1; /* RFP6 */
unsigned char :2; /* Reserved Bits */
unsigned char CTP6:1; /* CTP6 */
};

“:”有什么用?它甚至是运营商吗?我知道 unsigned char 'type' 是什么,但 unsigned char :2 是什么?请解释。
