C语言printf按二进制输出整数

#define PRINTF_BINARY_PATTERN_INT8 "%c%c%c%c%c%c%c%c,"
#define PRINTF_BYTE_TO_BINARY_INT8(i)    
    (((i) & 0x80ll) ? '1' : '0'), 
    (((i) & 0x40ll) ? '1' : '0'), 
    (((i) & 0x20ll) ? '1' : '0'), 
    (((i) & 0x10ll) ? '1' : '0'), 
    (((i) & 0x08ll) ? '1' : '0'), 
    (((i) & 0x04ll) ? '1' : '0'), 
    (((i) & 0x02ll) ? '1' : '0'), 
    (((i) & 0x01ll) ? '1' : '0')

#define PRINTF_BINARY_PATTERN_INT16 
    PRINTF_BINARY_PATTERN_INT8              PRINTF_BINARY_PATTERN_INT8
#define PRINTF_BYTE_TO_BINARY_INT16(i) 
    PRINTF_BYTE_TO_BINARY_INT8((i) >> 8),   PRINTF_BYTE_TO_BINARY_INT8(i)
#define PRINTF_BINARY_PATTERN_INT32 
    PRINTF_BINARY_PATTERN_INT16             PRINTF_BINARY_PATTERN_INT16
#define PRINTF_BYTE_TO_BINARY_INT32(i) 
    PRINTF_BYTE_TO_BINARY_INT16((i) >> 16), PRINTF_BYTE_TO_BINARY_INT16(i)
#define PRINTF_BINARY_PATTERN_INT64    
    PRINTF_BINARY_PATTERN_INT32             PRINTF_BINARY_PATTERN_INT32
#define PRINTF_BYTE_TO_BINARY_INT64(i) 
    PRINTF_BYTE_TO_BINARY_INT32((i) >> 32), PRINTF_BYTE_TO_BINARY_INT32(i)

使用

 int main(void)
 {
	 u32 number = 0x1FFFFFE;
	 printf("My Flag "	PRINTF_BINARY_PATTERN_INT32 "n",
	PRINTF_BYTE_TO_BINARY_INT32(number));
}

输出
