TUXEDO客户端开发基础问题
#include <stdio.h>
#include "atmi.h"
int main(int argc, char argv[])
{
char buf;
long len;
if(argc != 2) {
(void) fprintf(stderr, "Usage: simpcl string\n");
exit(1);
}//if argc

//初始化连接
if (tpinit((TPINIT ) NULL) == -1) {
(void) fprintf(stderr, "Tpinit failed\n");
exit(1);
}//if tpinit

len = strlen(argv[1]);
if((buf = (char ) tpalloc("STRING", NULL, len+1)) == NULL) {

(void) fprintf(stderr,"Error allocating send buffer\n");
tpterm();
exit(1);
}

//赋值
(void) strcpy(buf, argv[1]);

//调用服务
if(tpcall("TOUPPER", buf, 0, &&buf, &&len, 0)==-1){
(void) fprintf(stderr, "Can't send request to service TOUPPER\n");
tpfree(buf);
tpterm();
exit(3);
}

(void) fprintf(stdout, "Returned string is: %s\n", rcvbuf);
tpfree(buf);
tpterm();
return(0);
}

像这种例子都是只给TUXEDO服务传一个参数的，那如果我需要给服务传很多参数怎么办，比如，我需要给ITF_GETCSTINFO这样一个服务传客户的姓名、性别、年龄等，我该如何传呢？谢谢

这里没有专门的TUXEDO论坛，只好发到ORACLE了，时间紧急，知道的请务必讲一下，谢谢

传多个参数就用结构啊，tpalloc的时候用FML32格式，比如：

C/C++ code



         char                SendBuf[1024*3];
    FBFR32            *send, *rcv;
       long                      rcvLen;
    int                         ret;

    if (tpinit((TPINIT *) NULL) == -1)
    {
        (void) fprintf(stderr, "Tpinit failed\n");
        exit(1);
    }

    if ((send=(FBFR32 *)tpalloc("FML32",NULL,1024*1024*2))==NULL)
    {
            printf("tpalloc error!\n");
            return 0;
    }
        
    if ((rcv=(FBFR32 *)tpalloc("FML32",NULL,10000))==NULL)
    {
            printf("Error allocating receive buffer\n");
            tpfree((char *)send);
            tpterm();
            exit(1);
    }

......
    memcpy((void *)SendBuf,(void *)&a_struct_variable,sizeof(QueryReqStruc));

    Fadd32(send, THE_FIELDID, (char *)&a_struct_variable, sizeof(The_struct));

    ret = tpcall("servicename", (char *)send, 0, (char **)&rcv, &rcvLen, (long)0);
    if(ret == -1) {
            
.......
