@end example
@end ifset
@ifset is-Ada
@end ifset
@subheading STATUS CODES:
The @code{cfgetispeed()} function returns a code for baud rate.
@subheading DESCRIPTION:
The @code{cfsetispeed()} function stores a code for the terminal speed
stored in a struct termios. The codes are defined in @code{<termios.h>}

B1800, B2400, B4800, B9600, B19200, and B38400.
The @code{cfsetispeed()} function does not do anything to the hardware.
It merely stores a value for use by @code{tcsetattr()}.
@subheading NOTES:
Baud rates are defined by symbols, such as B110, B1200, B2400. The actual
number returned for any given speed may change from system to system.

B2400, B4800, B9600, B19200, and B38400.
The @code{cfgetospeed()} function does not do anything to the hardware.
It merely returns the value stored by a previous call to @code{tcgetattr()}.
@subheading NOTES:
Baud rates are defined by symbols, such as B110, B1200, B2400. The actual
number returned for any given speed may change from system to system.

@subheading NOTES:
This function merely stores a value in the @code{termios} structure. It
does not change the terminal speed until a @code{tcsetattr()} is done.
It does not detect impossible terminal speeds.

@unnumbered Preface
This is the User's Guide for the POSIX API support
provided in RTEMS.
The functionality described in this document is based
on the following standards:
@itemize @bullet
@item POSIX 1003.1b-1993.
@item POSIX 1003.1h/D3.
@end itemize
Much of the POSIX API standard is actually implemented in the
Cygnus Newlib ANSI C Library. Please refer to documentation on
Newlib for more information on what it supplies.
At this point, this is just beginning to become what it
ultimately should be.

@chapter Scheduler Manager
@section Introduction
The scheduler manager ...
The directives provided by the scheduler manager are:
@itemize @bullet
@item @code{sched_get_priority_min} -
@item @code{sched_get_priority_max} -
@item @code{sched_rr_get_interval} -
@item @code{sched_yield} -
@end itemize
@section Background
@subsection Priority
In the RTEMS implementation of the POSIX API, the priorities range from
the low priority of sched_get_priority_min() to the highest priority of
sched_get_priority_max(). Numerically higher values represent higher
priorities.
@subsection Scheduling Policies
The following scheduling policies are available:
@table @b
@item SCHED_FIFO
Priority-based, preemptive scheduling with no timeslicing. This is equivalent
to what is called "manual round-robin" scheduling.
@item SCHED_RR
Priority-based, preemptive scheduling with timeslicing. Time quantums are
maintained on a per-thread basis and are not reset at each context switch.
Thus, a thread which is preempted and subsequently resumes execution will
attempt to complete the unused portion of its time quantum.
@item SCHED_OTHER
Priority-based, preemptive scheduling with timeslicing. Time quantums are
maintained on a per-thread basis and are reset at each context switch.
@item SCHED_SPORADIC
Priority-based, preemptive scheduling utilizing three additional parameters:
budget, replenishment period, and low priority. Under this policy, the
thread is allowed to execute for "budget" amount of time before its priority
is lowered to "low priority". At the end of each replenishment period,
the thread resumes its initial priority and has its budget replenished.
