   * $nh(P) - transport protocol (upper case p)   * $nh(P) - transport protocol (upper case p)
  
-===== GeoIP module Pseudo-Variables =====+===== NDB_REDIS Module ===== 
 + 
 +==== $redis(res=>key) ==== 
 + 
 +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), the members of the array can be accessed by adding any of the above keys, after a value[n] key. The first value[n] references the element in the first array, while the next key references an element of the referenced array. 
 + 
 +Example: 
 + 
 +<code> 
 +redis_cmd("srvN", "GET foo", "r"); 
 +xlog("===== result type: $redis(r=>type) * value: $redis(r=>value)\n"); 
 +</code> 
 + 
 +==== $redisd(key) ==== 
 + 
 +Return the corresponding value for various defines from hiredis library. 
 + 
 +The key can be: 
 + 
 +  * rpl_str - return REDIS_REPLY_STRING 
 +  * rpl_arr - return REDIS_REPLY_ARRAY 
 +  * rpl_int - return REDIS_REPLY_INTEGER 
 +  * rpl_nil - return REDIS_REPLY_NIL 
 +  * rpl_sts - return REDIS_REPLY_STATUS 
 +  * rpl_err - return REDIS_REPLY_ERROR 
 + 
 +$redisd(rpl_XYZ) can be compared with $redis(r=>type). 
 + 
 +Example: 
 + 
 +<code> 
 +redis_cmd("srvN", "GET foo", "r"); 
 +if ($redis(r=>type) == $redisd(rpl_int)) { 
 +
 +</code> 
 + 
 +===== GeoIP Module =====
  
 ==== $gip(pvc=>key) ==== ==== $gip(pvc=>key) ====
Line 2012: Line 2064:
 </code> </code>
  
 +
 +===== sdpops module variables =====
 +
 +  *  $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 =====
 +
 +  * $sruid - return unique ID
 ===== $C(xy) - Foreground and background colors ===== ===== $C(xy) - Foreground and background colors =====
