同步调用

连接

redisContext* redisConnect(constchar*ip,intport);

发送命令并且获取响应

void *redisCommand(redisContext *c, const char *format, ...);

返回的结果结构体为

typedef struct redisReply {int type; /* REDIS_REPLY_* */long long integer; /* The integer when type is REDIS_REPLY_INTEGER */int len; /* Length of string */char *str; /* Used for both REDIS_REPLY_ERROR and REDIS_REPLY_STRING */size_t elements; /* number of elements, for REDIS_REPLY_ARRAY */struct redisReply **element; /* elements vector for REDIS_REPLY_ARRAY */
} redisRepl

type支持的值有

• REDIS_REPLY_STRING
• REDIS_REPLY_ARRAY
• REDIS_REPLY_INTEGER
• REDIS_REPLY_NIL
• REDIS_REPLY_STATUS
• REDIS_REPLY_ERROR

释放响应对象

void freeReplyObject(void *reply)
