请问这个错是什么原因呢?

[happy_swallow]

two or more data types in declaration of 'test'
函数是这样的:
test(int sock,struct connection *c,long policy,unsigned long try),请大家帮忙看看?

struct connection *c

可能是你定义了其它的变量名也叫test吧，最好把代码都帖出来，这样谁也看不出那有问题。

请问这样的定义不可以吗?

a.h中写了这样一些:
typedef unsigned long lest;
struct connection{
char *name;
lest policy;
struct connection *next;}
test(int sock,struct connection *c,long policy,lest try)
把这个.h包含在.c中编译就报错,请问为什么,很急.

[hpho]

typedef unsigned long lest;
struct connection{
char *name;
lest policy;
struct connection *next;
}; // <-- ';'

void test(int sock,struct connection *c,long policy,lest try)
{
}

谢谢你，hpho(),解决了！
