遇到编译问题,总是解决不了,向高手请教,写的是一个C语言抛出异常的代码
码如下:
接口(里面含有大量预处理内容):
#ifndef EXCEPT_INCLUDED
#define EXCEPT_INCLUDED
#include <setjmp.h>
#define T Except_T
typedef struct T
{
char *reason;
} T;
typedef struct Except_Frame Except_Frame;
struct Except_Frame
{
Except_Frame *prev;
jmp_buf env;
const char *file;
int line;
const T *exception;
};
enum
{
Except_entered = 0,
Except_raised,
Except_handled,
Except_finalized
};
#ifdef WIN32
__declspec(thread)
#endif
extern Except_Frame *Except_stack;
extern const Except_T Assert_Failed;
void Except_raise(const T *e, const char *file, int line);
#define RAISE(e) Except_raise( &(e), __FILE__, __LINE__ )
#define RERAISE Except_raise( Except_frame.exception,\
Except_frame.file, Except_frame.line )
#define RETURN\
switch ( Except_stack = Except_stack-> prev, 0 )\
default:\
return
#define TRY\
do\
{\
volatile int Except_flag;\
Except_Frame Except_frame;\
Except_frame.prev = Except_stack;\
Except_stack = &Except_frame;\
Except_flag = setjmp(Except_frame.env);\
if (Except_flag == Except_entered)\
{
#defineEXCEPT(e)\
if (Except_flag == Except_entered)\
Except_stack = Except_stack-> prev;\
}\
else if (Except_frame.exception == &(e))\
{\
Except_flag = Except_handled;
#define ELSE\
if (Except_flag == Except_entered)\
Except_stack = Except_stack-> prev;\
}\
else\
{\
Except_flag = Except_handled;
#define FINALLY\
if (Except_flag == Except_entered)\
Except_stack = Except_stack-> prev;\
}\\
if (Except_flag == Except_entered)\
{\
Except_flag = Except_finalized;
#define END_TRY\
if (Except_flag == Except_entered)\
Except_stack = Except_stack-> prev;\
}\
if (Except_flag == Except_raised)\
RERAISE;\
}while (0)
#undef T
#endif
实现代码:
#include <stdlib.h>
#include <stdio.h>
#include "assert.h "
#include "except.h "
#define T Except_T
#ifdef WIN32
__declspec(thread)
#endif
Except_Frame *Except_stack = NULL;
void Except_raise(const T *e, const char *file, int line)
{
Except_Frame *p = Except_stack;
assert(e);
if (p == NULL)
{
fprintf(stderr, "Uncaught exception ");
if (e-> reason)
fprintf(stderr, " %s ", e-> reason);
else
fprintf(stderr, " at 0x%p ", e);
if (file && line > 0)
fprintf(stderr, " raised at %s:%d\n ", file, line);
fprintf(stderr, "aborting...\n ");
fflush(stderr);
abort();
}
p-> exception = e;
p-> file = file;
p-> line = line;
Except_stack = Except_stack-> prev;
longjmp(p-> env, Except_raised );
}
这两段代码是基于接口与实现分离的形式,错误如下:
Compiling...
except.c

按照这个错误改
错误说的也够明白了啊

常量没付值吧
[解决办法]
Except_stack = Except_stack-> prev; \
} \ \ //---------

楼主，你也在看这段呢
我也在看，晕的不行，呵呵
不过这书挺有意思的倒是
[解决办法]
程序应该没有问题，我用 VC6 试着编译，结果如下：
--------------------Configuration: except - Win32 Debug--------------------
Compiling...
except.c
except.obj - 0 error(s), 0 warning(s)
