一个宏定义的错误，小弟看不懂，请高手进来看看，有一定的难度

[sh_liyu98]

#define PI_SAME(name, type) \
struct name { \
name() { } \
name(type value) { data = value; } \
name(const name & value) { data = value.data; } \
name & operator =(type value) { data = value; return *this; } \
name & operator =(const name & value) { data = value.data; return *this; } \
operator type() const { return data; } \
friend ostream & operator<<(ostream & s, const name & v) { return s << v.data; } \
friend istream & operator>>(istream & s, name & v) { return s >> v.data; } \
private: type data; \
}


#define PI_LOOP(src, dst) \
BYTE *s = ((BYTE *)&src)+sizeof(src); BYTE *d = (BYTE *)&dst; \
while (s != (BYTE *)&src) *d++ = *--s;

#define PI_DIFF(name, type) \
struct name { \

friend ostream & operator<<(ostream & s, const name & value) { return s << (type)value; } \
friend istream & operator>>(istream & s, name & v) { type val; s >> val; v = val; return s; }
private: type data; \
}
#if PBYTE_ORDER==PLITTLE_ENDIAN
PI_SAME(PInt16l, PInt16);
#elif PBYTE_ORDER==PBIG_ENDIAN
PI_DIFF(PInt16l, PInt16);
#endif

本代码来自于H323的开源代码，PWLIB中的，在编译中发现一个错误

哪个兄弟能帮我解释下这段代码是什么意思，中间有错误，我不知道怎么去修改
小弟不胜感激

[sh_liyu98]

都定义了

[lann64]

这一行 friend istream & operator>>(istream & s, name & v) { type val; s >> val; v = val; return s; }
后面少了个'\'，其他没什么错了。

[sh_liyu98]

更正下


#define PI_DIFF(name, type)\
class name { \
name() { } \
name(type value) { operator=(value); } \
name(const name & value) { data = value.data; } \
name & operator =(type value) { PI_LOOP(value, data); return *this; } \
name & operator =(const name & value) { data = value.data; return *this; } \
operator type() const { type value; PI_LOOP(data, value); return value; } \
friend ostream & operator<<(ostream & s, const name & value) { return s << (type)value; } \
friend istream & operator>>(istream & s, name & v) { type val; s >> val; v = val; return s; } \

private:\
type data; \
}

程序还是那两个错误

[KUCHIBUE]

同意 lann64(昆仑大鹏＠迦楼罗)

[KUCHIBUE]

还有,struct和class的定义后面应该有分号

[lann64]

没什么错误呀。
你编译的时候，前面定义了PInt16吗？
#include <iostream>
using namespace std;
加上了吗？

[greenteanet]

看看struct和class中是否少了';'

[sh_liyu98]

由于缺少了一个\\的问题

[jimmy212]

没找到错误!

[OOPhaisky]

看着头晕ing。。。
怎么定义了这么大的一个宏阿？？
