Hallo zusammen

Ich habe versucht, new und delete zu überladen, um ein Speicherverlustproblem in meinem Projekt zu beheben. Habe aber einen Kompilierungsfehler.

Derzeit ist dieser Code etwas schäbig

Hier ist meine HDR-Datei

#include <cstddef>
#include <iostream>
#include <list>
#include <stdarg.h>
#include <stdio.h>
using namespace std;
typedef unsigned int  DWORD;
void AddTrack(DWORD addr,  DWORD asize,  const char *fname, DWORD lnum);
char *OutputDebugString (const char *fmt, ...);
void RemoveTrack(DWORD addr);
void DumpUnfreed();

#ifdef _DEBUG
#define DEBUG_NEW new(__FILE__, __LINE__)
#define new DEBUG_NEW


   void *  operator new (unsigned int size, const char *file, int line)
  {
          void *ptr = (void *)malloc(size);
          AddTrack((DWORD)ptr, size, file, line);
          return(ptr);
  }
  /*inline void * operator new(unsigned int size)
  {
          void *ptr = (void *)malloc(size);
          AddTrack((DWORD)ptr, size, _FILE_,_LINE_);
          return(ptr);
  }*/
  void  operator delete(void *p)
  {
          RemoveTrack((DWORD)p);
          free(p);
  }

#endif


char *OutputDebugString (const char *fmt, ...)
{

char *p = NULL;
 size_t size = 1024;
 int n = 0;
 va_list ap;

 if((p = (char*) malloc(size)) == NULL)
 return NULL;

 while(1) {
  va_start(ap, fmt);
  n = vsnprintf(p, size, fmt, ap);
  va_end(ap);

 if(n > -1 && n < size)
return p;

/* failed: have to try again, alloc more mem. */
if(n > -1)      /* glibc 2.1 */
size = n + 1;
else            /* glibc 2.0 */
size *= 2;     /* twice the old size */

if((p = (char *)realloc (p, size)) == NULL)
return NULL;
}
}

typedef struct information {
DWORD   address;
DWORD   size;
char    file[64];
DWORD   line;
} ALLOC_INFO;

typedef list < ALLOC_INFO* > AllocList;
AllocList *allocList;




  void AddTrack(DWORD addr,  DWORD asize,  const char *fname, DWORD lnum)
  {
          ALLOC_INFO *info;

          if(!allocList) {
          //allocList = new AllocList;
            allocList = (AllocList*)malloc (sizeof (AllocList));
          }

          //info = new(ALLOC_INFO);
          info = (ALLOC_INFO*) malloc (sizeof (ALLOC_INFO));
          info->address = addr;
          strncpy(info->file, fname, 63);
          info->line = lnum;
          info->size = asize;
          allocList->insert(allocList->begin(), info);
  }

  void RemoveTrack(DWORD addr)
  {
          AllocList::iterator i;

          if(!allocList)
          if(!allocList)
                  return;
          for(i = allocList->begin(); i != allocList->end(); i++)
          {
                  if((*i)->address == addr)
                  {
                          allocList->remove((*i));
                          break;
                  }
          }
  }





void DumpUnfreed()
  {
          AllocList::iterator i;
          DWORD totalSize = 0;
          char buf[1024];

          if(!allocList)
                  return;

          for(i = allocList->begin(); i != allocList->end(); i++) {
                  sprintf(buf, "%-50s:\t\tLINE %d,\t\tADDRESS %d\t%d unfreed\n",
                          (*i)->file, (*i)->line, (*i)->address, (*i)->size);
                  OutputDebugString("%s",buf);
                  totalSize += (*i)->size;
          }
          sprintf(buf, "-----------------------------------------------------------\n");
          OutputDebugString("%s",buf);
          sprintf(buf, "Total Unfreed: %d bytes\n", totalSize);
          OutputDebugString("%s",buf);
  }

Und meine main.cpp ist

#include "mynew.h"
int main()
{

char *ptr = new char;
DumpUnfreed();

return 0;
}

Wenn ich versuche zu kompilieren, erhalte ich den folgenden Fehler

[root@dhcppc0 new]# !g
g++ main.cpp -D_DEBUG
mynew.h:25: error: declaration of ‘operator new’ as non-function
main.cpp: In function ‘int main()’:

Ich weiß, dass mit meinen #Defines etwas nicht stimmt, aber ich bin mir nicht sicher, was falsch ist.

Kann jemand mich bitte rauspressen
