IHttpUser implementers are responsible for memory management with this data; therefore, IHttpUser implementers that use dynamic memory allocation must release or call delete on the PCWSTR pointer when it is no longer needed.

IHttpUser implementers are responsible for memory management with this data; therefore, IHttpUser clients must not release or call delete on the returned PCWSTR pointer when this data is no longer needed. Furthermore, clients must not cast this data to a pointer that is not a const or change the state of the memory referenced by this PCWSTR; otherwise, an access violation will be thrown or the data will become invalid.

Example

The following code example demonstrates how to create an HTTP module that clears the response headers and body and then returns user information to the client as an XML document.

The above code writes XML to the response stream similar to the following.

<?xml version="1.0" ?>
<user userName="DOMAIN\user" />

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 Request-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.
