远程过程调用：如何在XDR文件中声明同一程序的两个版本
||
我正在编写一个程序，该程序使RPC打印一条消息，该消息作为参数发送给远程功能。远程函数不应返回任何内容，但是出于好奇，我已将远程函数设计为返回整数。
无论如何，一切正常，我能够远程打印消息。现在，我正在尝试在XDR文件中创建程序的两个版本（只是好奇！！），但对我来说不起作用。
这是我的新XDR文件
anirudh@anirudh-Aspire-5920:~/Documents/C/DS/RPC$ cat spec.x
program MSGPROG{
version PRINTMSGVERSION{
int PRINTMSG(string) = 1;
} = 1;
version PRINTMSGVERSION{
int PRINTMSG(string) = 1;
} = 2;
} = 0x2000001;
anirudh@anirudh-Aspire-5920:~/Documents/C/DS/RPC$ cat server.c
#include<stdio.h>
#include \"spec.h\"
int *printmsg_1_svc(char **msg,struct svc_req * sr){
static int ret;
printf(\"version = 1--%s\\n\",*msg);
ret = 1;
return &ret;
}
int *printmsg_2_svc(char **msg,struct svc_req * sr){
static int ret;
printf(\"version = 2--%s\\n\",*msg);
ret = 1;
return &ret;
}
anirudh@anirudh-Aspire-5920:~/Documents/C/DS/RPC$ rpcgen -C spec.x
anirudh@anirudh-Aspire-5920:~/Documents/C/DS/RPC$ gcc server.c spec_svc.c -o ani_server -lnsl
