| 释义 | LocalFlags 语法： C++ UINT WINAPI LocalFlags( __in HLOCAL hMem ); LocalFlags功能 信息检索指定的本地内存对象。 注意：此功能仅提供了兼容性与16位的Windows版本。新的应用程序应该使用堆函数。有关更多信息，请参见备注。 参数 hMem [in] 句柄到本地内存对象。这是处理不论是由LocalAlloc或LocalReAlloc函数返回。 返回值 如果函数成功，返回值指定分配值的内存对象和锁计数。 如果函数失败，返回值是LMEM_INVALID_HANDLE，显示本地的处理是无效的。为了获得更多错误信息，调用GetLastError。 备注 该低的低的返回值为词序字节包含该对象的锁计数。从该返回值的锁计数，使用与位与(＆)运算的LMEM_LOCKCOUNT面具。与LMEM_FIXED分配的内存对象锁计数始终为零。 高，低，返回值的命令字的顺序字节表示的内存对象的分配值。它可以是零或LMEM_DISCARDABLE。 当地的职能，并提供更大的开销比其他内存管理功能较少的功能。新的应用程序应该使用堆文档指出，除非当地的职能应常用的功能。有关更多信息，请参阅全局和局部的功能。 要求： 最低支持：client－Windows 2000专业版 最低支持server－Windows 2000服务器 HeaderWinbase.h(头文件：winuser.h) LibraryKernel32.lib DLLKernel32.dll 参见 全局和局部功能 GlobalFlags LocalAlloc LocalDiscard LocalLock LocalReAlloc LocalUnlock 内存管理功能 如果有任何问题和意见，请发送给微软(wsddocfb@microsoft.com) 生成日期：2009年8月27日 ＝＝英文原文＝＝LocalFlags Function Retrieves information about the specified local memory object. Note This function is provided only for compatibility with 16-bit versions of Windows. New applications should use the heap functions . For more information, see Remarks. Syntax C++ UINT WINAPI LocalFlags( __in HLOCAL hMem ); Parameters hMem [in] A handle to the local memory object. This handle is returned by either the LocalAlloc or LocalReAlloc function. Return Value If the function succeeds, the return value specifies the allocation values and the lock count for the memory object. If the function fails, the return value is LMEM_INVALID_HANDLE, indicating that the local handle is not valid. To get extended error information, call GetLastError . Remarks The low-order byte of the low-order word of the return value contains the lock count of the object. To retrieve the lock count from the return value, use the LMEM_LOCKCOUNT mask with the bitwise AND (&) operator. The lock count of memory objects allocated with LMEM_FIXED is always zero. The high-order byte of the low-order word of the return value indicates the allocation values of the memory object. It can be zero or LMEM_DISCARDABLE. The local functions have greater overhead and provide fewer features than other memory management functions. New applications should use the heap functions unless documentation states that a local function should be used. For more information, see Global and Local Functions .
