loadrunner winsocket 测试问题！

jdzjdz123

这几天一直在弄一个loadrunner的cs测试脚本，使用windows socket的cs脚本，弄了几天终于弄出点东东来。
偶的测试脚本如下：

unsigned char uc_key[9];
unsigned char pinkey[17];
unsigned char *mask = (unsigned char *) "19?2<8276:=0839;";

Action()
{
   
    char acTest[512];
    char acTest2[512];
    char* pcTest3;
    int i;
    char pinblock[17];
    char acct[26];
    char acc1[17];
    char balance[12];
    char seq_str[6];
     int i_seq=1;
    char socket_desc[10];
    int handler;
    int ret;   


    lr_load_dll("mydll.dll");

    i_seq++;
   
    sprintf(seq_str,"%.5d",i_seq);
    sprintf(socket_desc,"sock%.5d",i_seq);
    //char  *filename="1.out";
    //long  filestream;
   
    //filestream=fopen(filename,"w");
    lrs_create_socket(socket_desc, "TCP", "RemoteHost=192.168.101.79:7001", LrsLastArg);
   
   

    //生成发送的串
    sprintf(acTest,"ABCDEA");
    strcat(acTest,"1205");
    strcat(acTest,"RQK");
    strcat(acTest,seq_str);
    strcat(acTest,seq_str);
    strcat(acTest,"0000000000000000O");
   

    //指定发送的串
    lrs_set_send_buffer (socket_desc, acTest, strlen(acTest));
    //发送，由于之前运行了lrs_set_send_buffer，所以这里的"buf0"参数无效

    lrs_send(socket_desc, "buf0", LrsLastArg);

    lrs_set_recv_timeout2(0,0);
    //接收返回的串
    lrs_receive(socket_desc, "buf1", LrsLastArg);
    //把返回的串放到变量中
    pcTest3=lrs_get_received_buffer (socket_desc, 0, -1, NULL);

    //fprintf(filestream,"recv=[%s]\n",pcTest3);
    memcpy(uc_key,pcTest3+18,8);
    unshuffle_key(uc_key);

        pinkey[2*i]='3';
        pinkey[2*i+1]=uc_key;
    }

发送一个报文向服务器取密钥，然后根据密钥加密一些重要字段，再发送其他交易。
socket短连接通讯方式，其实就是模拟atm机器上的交易。

没看明白!多少给点指示吧脚本大概是什么功能

刚才的脚本如果执行一次是没问题的，可是当我执行2次的时候，就运行报错了。
