将字符串复制到剪贴板内存泄漏

Question

我写了一个c程序，它只是创建一个SQL查询并将其复制到剪贴板。但是，程序似乎会产生内存泄漏并导致计算机崩溃。我不知道如何解决这个问题。

//copies the given string TO the clipboard
int copyStringToClipboard(char * source)
{
   int ok = OpenClipboard(NULL);   
   if (!ok) return MY_ERROR;
   /* else */
   HGLOBAL clipbuffer;
   char * buffer;
   EmptyClipboard();
   clipbuffer = GlobalAlloc(GMEM_DDESHARE, strlen(source)+1);
   buffer = (char*)GlobalLock(clipbuffer);
   strcpy(buffer, source);
   GlobalUnlock(clipbuffer);
   SetClipboardData(CF_TEXT,clipbuffer);
   CloseClipboard();
}

char *replace_str(char *str, char *orig, char *rep)
{
  static char buffer[MAX_PATH];
  char *p;
  if(!(p = strstr(str, orig)))  // Is 'orig' even in 'str'?
    return str;
  strncpy(buffer, str, p-str); // Copy characters from 'str' start to 'orig' st$
  buffer[p-str] = '\0';
  sprintf(buffer+(p-str), "%s%s", rep, p+strlen(orig));
  return buffer;
}
