Editing RTLinux (section)

== Functions ==
Most RTLinux functions are in a set of loadable kernel modules that provide optional services and levels of abstraction. These modules include:

# rtl sched - a priority scheduler that supports both a "lite POSIX" interface described below and the original V1 RTLinux API.
# rtl time - which controls the processor clocks and exports an abstract interface for connecting handlers to clocks.
# rtl posixio - supports POSIX style read/write/open interface to device drivers.
# rtl fifo - connects RT tasks and interrupt handlers to Linux processes through a device layer so that Linux processes can read/write to RT components.
# semaphore - a contributed package by Jerry Epplin which gives RT tasks blocking semaphores.
# POSIX mutex support is planned to be available in the next minor version update of RTLinux.
# mbuff is a contributed package written by Tomasz Motylewski for providing shared memory between RT components and Linux processes.
