CGlobalModule::Terminate Method

IIS 7.0

Represents the method that IIS calls when a global module has completed processing.

virtual VOID Terminate(
) = 0;

This method takes no parameters.

IIS calls the Terminate method for a CGlobalModule before a module is unloaded.


Developers should use the Terminate method to remove implementations of CGlobalModule classes from memory.


The following code example demonstrates how to create a simple "Hello World" global-level HTTP module. The module defines an exported RegisterModule function that creates an instance of a class that is derived from CGlobalModule. If the class cannot be created, the function exits with an error code; otherwise, the function calls the IHttpModuleRegistrationInfo::SetRequestNotifications method to register for the GL_PRE_BEGIN_REQUEST notification.

When a GL_PRE_BEGIN_REQUEST notification occurs, IIS calls the module's CGlobalModule::OnGlobalPreBeginRequest method to process the notification. The method calls a private method to write an event to the application log of the Event Viewer, and then it returns GL_NOTIFICATION_CONTINUE to notify IIS to continue processing other notifications. When processing is complete, IIS calls the module's Terminate method to remove the class from memory.

Your module must export the RegisterModule function. You can export this function by creating a module definition (.def) file for your project, or you can compile the module by using the /EXPORT:RegisterModule switch. For more information, see Walkthrough: Creating a Global-Level HTTP Module By Using Native Code.

You can optionally compile the code by using the __stdcall (/Gz) calling convention instead of explicitly declaring the calling convention for each function.
