| 释义 | Heap32ListFirst 语法： C++ BOOL WINAPI Heap32ListFirst( __in HANDLE hSnapshot, __inout LPHEAPLIST32 lphl ); Heap32ListFirst功能 获取信息的第一堆已被指定的进程分配。 参数 hSnapshot [in] 一个句柄，从先前调用CreateToolhelp32Snapshot函数返回的快照。 lphl [ in , out ] 一个 HEAPLIST32结构的指针。 返回值 返回TRUE堆列表第一项已被复制到缓冲区或否则返回FALSE。在ERROR_NO_MORE_FILES错误值返回时，GetLastError函数不存在或堆名单快照不包含堆列表信息。 备注 调用应用程序必须设置HEAPLIST32 dwSize成员的大小，以字节为单位的结构。 Heap32ListFirst变化dwSize，以书面向结构的字节数。这将永远不会大于dwSize初始值，但它可能会更小。如果该值较小，不依赖于任何成员的偏移量大于此值的值。 检索有关堆中的清单其他堆信息，请使用Heap32ListNext功能。 实例 有关示例，请参见遍历堆名单。 要求： 最低支持：client－Windows 2000专业版 最低支持server－Windows 2000服务器 HeaderTlhelp32.h LibraryKernel32.lib DLLKernel32.dll 参见 CreateToolhelp32Snapshot 堆列表和堆散步 Heap32ListNext HEAPLIST32 工具帮助函数 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＝＝Heap32ListFirst Function Retrieves information about the first heap that has been allocated by a specified process. Syntax C++ BOOL WINAPI Heap32ListFirst( __in HANDLE hSnapshot, __inout LPHEAPLIST32 lphl ); Parameters hSnapshot [in] A handle to the snapshot returned from a previous call to the CreateToolhelp32Snapshot function. lphl [in, out] A pointer to a HEAPLIST32 structure. Return Value Returns TRUE if the first entry of the heap list has been copied to the buffer or FALSE otherwise. The ERROR_NO_MORE_FILES error value is returned by the GetLastError function when no heap list exists or the snapshot does not contain heap list information. Remarks The calling application must set the dwSize member of HEAPLIST32 to the size, in bytes, of the structure. Heap32ListFirst changes dwSize to the number of bytes written to the structure. This will never be greater than the initial value of dwSize, but it may be smaller. If the value is smaller, do not rely on the values of any members whose offsets are greater than this value. To retrieve information about other heaps in the heap list, use the Heap32ListNext function. Examples For an example, see Traversing the Heap List .
