我在头文件中定义 typedef struct { ...; }A; typedef struct { ...; }B; 在C文件中定义 int func() { A* pA = NULL; B* pB = NULL; ....; } 用gcc编译时报 parse error before `pA' parse error before `pB' 什么情况，真是郁闷

定义结构体： typedef struct trie_node { char *data; trie_node *branch[node_num]; }TRIE_NODE; 程序在如下函数编译中出错： parse error before `*' TRIE_NODE *initial_trie() { return NULL; } 请指点。。。多谢！

（原标题为：求解：一个菜鸟编程中的问题！） 编写了一个shell命令cp 代码如下： #include #include #include #include #define maxOnce 1024 int main(int argc,char * argv[]) { int fdsrc,fddist; char buf[maxOnce]; char buf1[maxOnce]; int size; if(argc!=3) printf("error for input\n"); if((fdsrc=open(argv[1],O_RDONLY)==-1) perror("error for open\n ");//出错...

今天在/var/log/message里面发现大量错误 dhcpd:abandoning ip address xxx.xxx.xxx.xxx:pinged before offer 这个是什么原因啊

代码编译总是出错：部分代码如下： #include /*标准输入输出定义*/ #include /*标准函数库定义*/ #include /*Unix标准函数定义*/ #include /**/ #include /**/ #include /*文件控制定义*/ #include /*PPSIX终端控制定义*/ #include /*错误号定义*/ #include

VTLs: Assess before you commit Q: My backups are slow and unreliable. I've heard that putting in disk, in the form of a VTL, will solve my problems. Are there any gotchas to watch out for? By Noemi Greyzdorf January 12, 2007—A virtual tape library (VTL) is one way that disk can be integrated into a backup system. Since backing up to disk has become a more-viable solution in the past few years,...
