我正在尝试将rpc客户端的字符指针发送到rpcgen中的服务器,以下是服务器和客户端程序
RPC gen的RPC程序
struct clientinput {
char * optype;
char * word;
};
program DICTIONARY_PROG {
version DICTIONARY_VERS {
int USEDICTIONARY(clientinput) = 1;
} = 1;
} = 0x23451113;
RPC服务器
#include "dictionary.h"
int *
usedictionary_1_svc(clientinput *argp, struct svc_req *rqstp)
{
static int result;
char *optype = (char*)malloc (10);
char *word = (char*)malloc (10);
char *a = argp->optype;
char *b = argp->word;
printf("Optype is %s\n", a);
printf("Word is %s\n", b);
printf("The optype is %s\n", strcpy(optype, argp->optype));
printf("The word is %s\n", strcpy(word, argp->word));
/*
* insert server code here
*/
return &result;
}
RPC客户端
#include "dictionary.h"
void
dictionary_prog_1(char *host, char *optype, char *word)
{
CLIENT *clnt;
int *result_1;
clientinput usedictionary_1_arg;
//strcpy(usedictionary_1_arg.optype, optype);
//strcpy(usedictionary_1_arg.word, word);
usedictionary_1_arg.optype = optype;
usedictionary_1_arg.word = word;
printf("Optype input is %s\n",usedictionary_1_arg.optype);
printf("Word input is %s \n",usedictionary_1_arg.word);
#ifndef DEBUG
clnt = clnt_create (host, DICTIONARY_PROG, DICTIONARY_VERS, "udp");
if (clnt == NULL) {
clnt_pcreateerror (host);
exit (1);
}
#endif /* DEBUG */
result_1 = usedictionary_1(&usedictionary_1_arg, clnt);
if (result_1 == (int *) NULL) {
clnt_perror (clnt, "call failed");
}
#ifndef DEBUG
clnt_destroy (clnt);
#endif /* DEBUG */
}
int
main (int argc, char *argv[])
{
char *host, *optype, *word;
if (argc < 2) {
printf ("usage: %s server_host\n", argv[0]);
exit (1);
}
host = argv[1];
optype = argv[2];
word = argv[3];
dictionary_prog_1 (host,optype,word);
exit (0);
}
这是服务器端的输出
Optyep is a
Word is e
The optype is a
The word is e
我遇到的问题是,只有我从服务器传递给客户端的字符指针的第一个字符才会被打印出来。我尝试过使用字符指针的可能组合,但找不到原因。那么有人可以帮我找出原因吗?
