Release函數
Release英文解釋
IUnknown::Release Decreases the reference count of the interface by 1.
ULONG Release();
Parameters:
None
Return Values:
Returns the new reference count. This value is for diagnostic and testing purposes only.
Remarks:The object that exports the interface deallocates itself when its total reference count reaches 0. Use the IUnknown::AddRef method to increase the interface's reference count by 1.
Applications must call this method to release only those interfaces that were explicitly created in a previous call to IUnknown::AddRef,IUnknown::QueryInterface, or a creation function, such as Direct3DCreate9.
Requirements:
Header: Declared in Unknwn.h.
Release中文解釋
作用
將dx接口的數量減1,即釋放當前接口
ULONG Release(VOID);
返回新的接口數。 此數值緊用於診斷和測試。
當繼承接口而來的對象的總引用數量達到0時,他會釋放自己。使用IUnknown::AddRef 函數可以增加
應用程序必須調用此函數釋放這些接口,這些接口包括之前調用 IUnknown::AddRef IUnknown::QueryInterface產生的,也包括通過一個產生函數比如Direct3DCreate9,產生的。

Release定義
Release在QC中
QC是Quality Center 的縮寫.
A Releaserepresent a group of changes in an application ,which are ready for distribution at the same time.
[1]
在Quality Center中,人們常常需要辨析Cycle 和Release,這裏的Cycle的釋義為:
A cyclerepresents a development and QA cycle based on the project timeline.
Release在dhvp中
1.client廣播discover報文尋找dhcp服務器
2.dhcp-server回覆offer報文
3.clinet正式發送request報文請求地址
4.server回覆ack
這是整個dhcp獲取ip地址的基本流程
但是在某些情況下client在獲取dhcp-server給其分配的地址後會放棄該地址,
此時,client主動放棄地址就會向dhcp發送release報文解約。
