什么是资源泄漏？？？

[Dekn]

难道是内存泄漏？？

对，资源有很多，内存只是其中之一，像句柄，GDI等很多，资源泄漏就是资源没释放。

资源通常指系统的对象。例如GDI对象句柄、内存句柄等等。一些分配和复制的操作函数的文档中说明了调用者需要用一些代码释放函数分配的资源。
下面的代码用CopyHandle复制了内存句柄，然后用GlobalFree释放。
void CMyPrintView::OnFilePrintSetup()
{
// Ask the user which printer they want to use.
CPrintDialog pd(
FALSE,
PD_ALLPAGES | PD_USEDEVMODECOPIES |
PD_NOPAGENUMS | PD_HIDEPRINTTOFILE | PD_NOSELECTION,
this);

// Make sure we don't accidentally create a device context
pd.m_pd.Flags &= ~PD_RETURNDC; // Reset flag set by constructor.

// Force the CPrintDialog to use our device mode & name.
pd.m_pd.hDevMode = CopyHandle(m_hDevMode);
pd.m_pd.hDevNames = CopyHandle(m_hDevNames);

// Display the dialog box and let the user make their selection.
if (pd.DoModal() == IDOK)
{
// The user clicked OK
// (and POSSIBLY changed printers).

// In any case, the CPrintDialog logic made a copy of the original
// DEVMODE/DEVNAMES that we passed it and applied the user's
// changes to that copy and discarded the original copy we passed
// it. (NOTE: If the user had clicked CANCEL instead, the original
// values we passed would have been returned unchanged).
GlobalFree(m_hDevMode); // Free old copies.
GlobalFree(m_hDevNames); // Free old copies.

m_hDevMode = CopyHandle(pd.m_pd.hDevMode); // Save new copies.
m_hDevNames = CopyHandle(pd.m_pd.hDevNames); // Save new copies.
}

// Regardless of whether the user clicked OK or CANCEL,
// we need to ALWAYS do a GlobalFree of CPrintDialog's
// m_pd.hDevMode and m_pd.hDevNames upon return from
// DoModal in order to prevent a resource leak.
GlobalFree(pd.m_pd.hDevMode); // Because DoModal was called,
GlobalFree(pd.m_pd.hDevNames); // we need to free these.
}

包括很多啊，内存，图形设备接口资源等
