<concept id="GUID-9BB736AD-1224-587B-AC8C-355E7C8AEDC6" xml:lang="en"><title>Same-thread

services</title><shortdesc>Describes asynchronous services provided by same thread code.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>Sometimes, services are presented as asynchronous even when they are provided

by code in the same thread as its client.</p>

<p>Symbian platform’s asynchronous services are so easy to use that it’s often

convenient to code some long-running background operations as an asynchronous

service, which in other operating systems would be coded using a separate

thread.</p>

<p>It can also be convenient to define a high level class that can pass on

requests to an asynchronous service provider in the Kernel. The class presents

an asynchronous interface to its clients, but is intended to run in the same

thread.</p>
