这就是我的配置系统。
不需要特定的config结构。使用者直接从环境变量取。
配置文件：
#SENDSIZE=1500
#服务器守候端口
SERVICE=11655
#认证服务器
CA_D_NODE=1


使用：
       p=getenv("SERVICE");
        if(!p || !*p) {
                ShowLog(1,"缺少环境变量 SERVICE ,不知守候哪个端口！");
                quit(3);
        }
//测试端口是否被占用
        sock=tcpopen("localhost",p);
        if(sock>-1) {
                ShowLog(1,"端口 %s 已经被占用",p);
                close(sock);
                sock=-1;
                quit(255);
        }


完整的配置程序：
if(fname && NULL != (fd=fopen(fname,"r"))) {
                err=0;
                while(!ferror(fd)){
                        fgets(buffer,sizeof(buffer),fd);
                        if(feof(fd)) break;
                        TRIM(buffer);
                        i=skipblk(buffer)-buffer;
                        strsubst(buffer,i,(char *)0);
                        if(!*buffer || *buffer=='#') continue;
                        i=substitute_env(buffer);
                        if(i) {
                                fprintf(stderr,"%s",buffer);
                                fclose(fd);
                                reg_free();
                                return i;
                        }
#ifdef WIN32
                        putenv(buffer);
#else
                        cp=strdup(buffer);
                        putenv(cp);
#endif
                }
                reg_free();
                fclose(fd);
