关于APUE第一个程序编译出错问题，在线等～

[xiyangbu]

从APUE的书上抄了第一个程序1－1，ourhdr.h 我是从课本后面的附录上面打上的，然后放在了／usr／include/中，程序存储为ls.c，程序如下：
#include <sys/types.h>
#include <dirent.h>
#include "ourhdr.h"

int
main(int argc, char *argv[])
{
DIR *dp;
struct dirent *dirp;

if(argc!=2)
err_quit("a single argument (the directory name)is required");

if((dp=opendir(argv[1]))==NULL)
err_sys("can't open %s",argv[1]);
while((dirp=readdir(dp))!=NULL)
printf("%s\n",dirp->d_name);

closedir(dp);
exit(0);
}

编译：gcc ls.c ，出错问题如下：
[root@localhost ~]# gcc ls.c
ls.c: 在函数 ‘pr_mask’ 中：
ls.c:7: 错误：expected ‘;’, ‘,’ or ‘)’ before ‘{’ token
ls.c:21: 错误：原型函数定义中使用了旧式参数声明
ourhdr.h:35: 错误：省略了形参的名字
[root@localhost ~]#
大家帮忙看看是什么问题？谢～～

你应该把那一部分也贴出来.

好像是我的ourhdr.h不完全是吗？在我的附录里，ourhdr.h只是这样的，但是后面还有两个标准出错的处理函数，是不是应该也把这一部分给包含到ourhdr.h的头文件中阿？

[xiyangbu]

这个问题得到了解决。ourhdr.h需要把后面的标准出错函数包含进来，
ls.c: 在函数 ‘pr_mask’ 中：
ls.c:7: 错误：expected ‘;’, ‘,’ or ‘)’ before ‘{’ token
这个问题是由于在定义语句的时候没有加 ；
此处：
void pr_mask(const char *) /*Program 10.10*/
Sigfunc *signal_intr(int, Sigfunc *); /*Program 10.13*/
