接收新任务，两个set 的不同

int t_keyback_set(keyback_para_t key_para)
    {
        
    char *buf;
    char temp=(char)strtol(key_para,NULL,16); //----
    char i[1+sizeof(temp)] = {0x02};
    memcpy(i+1, &temp, sizeof(temp));
    int ret = t_run(KEYBACK_TEST, i, sizeof(i), &buf);
    if(buf != NULL)
    {
     free(buf);
     }
     return ret;
    }



与下面的相比：：

没有用strtol()函数：

int t_calitemp_set(calitemp_t calitemp)
   {
          char *buf;
         char i[1+sizeof(calitemp_t)] = {0x02};
       memcpy(i+1, calitemp, sizeof(calitemp_t));
         int ret = t_run(CALI_TEMP, i, sizeof(i), &buf);
         if(buf != NULL)
         {
         　printf("test is normal \n");
            free(buf);
         }
         return ret;
       }
