+ | ==== $redis(res=> | ||
+ | |||
+ | Access the attributes of the Redis response. | ||
+ | |||
+ | The key can be: | ||
+ | |||
+ | * type - type of the reply (as in hiredis.h) | ||
+ | * value - the value returned by REDIS server; | ||
+ | * info - in case of error from REDIS, it will contain an info message. | ||
+ | |||
+ | If reply type is an array (as in hiredis.h), there are other keys available: | ||
+ | |||
+ | * size - returns number of elements in the array. | ||
+ | |||
+ | * type[n] - returns the type of the nth element in the array. type - returns array type. | ||
+ | |||
+ | * value[n] - returns value of the nth element. value - returns null for an array. You need to get each element by index. | ||
+ | |||
+ | In case one of the members of the array is also an array (for example calling SMEMBERS in a MULTI/EXEC transaction), | ||
+ | |||
+ | Example: | ||
+ | |||
+ | < | ||
+ | redis_cmd(" | ||
+ | xlog(" | ||
+ | </ | ||
+ | |||
+ | ==== $redisd(key) ==== | ||
+ | |||
+ | Return the corresponding value for various defines from hiredis library. | ||
+ | |||
+ | The key can be: | ||
+ | |||
+ | * rpl_str - return REDIS_REPLY_STRING | ||
+ | * rpl_arr - return REDIS_REPLY_ARRAY | ||
+ | * rpl_int - return REDIS_REPLY_INTEGER | ||
+ | * rpl_nil - return REDIS_REPLY_NIL | ||
+ | * rpl_sts - return REDIS_REPLY_STATUS | ||
+ | * rpl_err - return REDIS_REPLY_ERROR | ||
+ | |||
+ | $redisd(rpl_XYZ) can be compared with $redis(r=> | ||
+ | |||
+ | Example: | ||
+ | |||
+ | < | ||
+ | redis_cmd(" | ||
+ | if ($redis(r=> | ||
+ | } | ||

+ | |||
+ | * $sdp(body) - full SDP body (read only) | ||
+ | * $sdp(sess_version) - sess-version -attribute from SDP o= -line. When set to special value -1, current value is incremented. (read + write) | ||
+ | |||
+ | ===== kex module variables ===== | ||
