Extensions</title><prolog><metadata><keywords/></metadata></prolog><conbody>
<p>POSIX real-time extensions (based on <xref href="http://en.wikipedia.org/wiki/POSIX" scope="external">POSIX 1003.1b</xref>) define extensions such as timers, priority
scheduling, real-time signals, semaphores, memory queues, shared memory and
memory locking that are useful for development of real-time systems. Extensions
such as, timers and shared memory are supported by the <xref href="http://refspecs.freestandards.org/LSB_3.1.0/LSB-Core-generic/LSB-Core-generic/librt.html" scope="external">Librt library</xref>, which conforms to the Linux Standard
Base (LSB) 3.1 Specification. The Symbian platform supports the Librt library,
which enables Symbian Developers to port Librt-based applications onto the
Symbian platform quickly and easily.</p>
