WINDOWS下获得DLL所在目录的代码

static char* getRunningPath(const char* pExe, char* pBuffer, const UINT appPathSize)
{
  if (GetModuleFileNameA(GetSelfModuleHandle(), pBuffer, appPathSize) == 0)
  {
  return NULL;
  }
  return pBuffer;
}

//windows下获取当前dll的句柄
static HMODULE GetSelfModuleHandle()
{
  MEMORY_BASIC_INFORMATION mbi;
  return ((::VirtualQuery(GetSelfModuleHandle, &mbi, sizeof(mbi)) != 0) ? (HMODULE)mbi.AllocationBase : NULL);
}
static char* getRunningPath(const char* pExe, char* pBuffer, const UINT appPathSize)
{
  if (GetModuleFileNameA(
        (pExe != NULL && strlen(pExe) > 0) ? NULL : GetSelfModuleHandle(),
        pBuffer, appPathSize) == 0)
  {
  return NULL;
  }
  return pBuffer;
}
