### Description

Detected that a command like this was not returning <0 ``` if(redis_cmd("test", "HSET dd field1", "r")) { [...] } ``` Same command on redis-cli: ``` # redis-cli 127.0.0.1:6379> HSET dd field1 (error) ERR wrong number of arguments for 'hset' command ```

### Troubleshooting

#### Reproduction

I've added some debug to the code and I find out that the command is returning: ``` Apr 23 10:55:02 spce proxy[12880]: DEBUG: ndb_redis [redis_client.c:956]: redisc_exec(): rpl->rplRedis->type:3 ``` That's an INTEGER. From hiredis/read.h: ``` #define REDIS_REPLY_INTEGER 3 #define REDIS_REPLY_NIL 4 #define REDIS_REPLY_STATUS 5 #define REDIS_REPLY_ERROR 6 ``` I've created a simple test code to check the same command: ``` #include <stdio.h> #include <stdarg.h> #include "hiredis.h"

void check(redisContext *c, const char *cmd, ...) { va_list ap; va_start(ap,cmd); redisReply *r = redisvCommand(c, cmd, ap); va_end(ap);

if(r == NULL) { printf("reply NULL\n"); } printf("reply->type:%d\n", r->type); freeReplyObject(r); }

int main(void) { redisContext *c = redisConnect("127.0.0.1", 6379);

if (c == NULL || c->err) { if (c) { printf("Error: %s\n", c->errstr); } else { printf("Can't allocate redis context\n"); } return 1; } check(c, "HSET dd field"); redisFree(c); return 0; } ``` ``` root@spce:/usr/local/devel# cc t.c -o t -lhiredis -I/usr/include/hiredis root@spce:/usr/local/devel# ./t reply->type:6 ``` No problems there. The reply is ERROR.
