The device- and class- specific functions manager is ...
The directives provided by the device- and class- specific functions
manager are:
@itemize @bullet
@item @code{cfgetispeed} - Reads terminal input baud rate
@item @code{cfgetospeed} - Reads terminal output baud rate
@item @code{cfsetispeed} - Sets terminal input baud rate
@item @code{cfsetospeed} - Set terminal output baud rate
@item @code{tcgetattr} - Gets terminal attributes
@item @code{tcsetattr} - Set terminal attributes
@item @code{tcsendbreak} - Sends a break to a terminal
@item @code{tcdrain} - Waits for all output to be transmitted to the terminal
@item @code{tcflush} - Discards terminal data
@item @code{tcflow} - Suspends/restarts terminal output
@item @code{tcgetpgrp} - Gets foreground process group ID
@item @code{tcsetpgrp} - Sets foreground process group ID
@end itemize
@section Background

This section details the device- and class- specific functions manager's

@subsection cfgetispeed - Reads terminal input baud rate
@subheading CALLING SEQUENCE:
@ifset is-C
@example
#include <termios.h>
int cfgetispeed(
const struct termios *p
);
@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>}
by the macros BO, B50, B75, B110, B134, B150, B200, B300, B600, B1200,
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.

@subheading STATUS CODES:
The @code{cfgetospeed()} function returns the termios code for the baud rate.
@subheading DESCRIPTION:
The @code{cfgetospeed()} function returns a code for the terminal speed
stored in a @code{struct termios}. The codes are defined in @code{<termios.h>}
by the macros BO, B50, B75, B110, B134, B150, B200, B300, B600, B1200, B1800,
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.

@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.

@section Background
@subsection Signal Delivery
Signals directed at a thread are delivered to the specified thread.
Signals directed at a process are delivered to a thread which is selected
based on the following algorithm:
@enumerate
@item If the action for this signal is currently @code{SIG_IGN},
then the signal is simply ignored.
@item If the currently executing thread has the signal unblocked, then
the signal is delivered to it.
@item If any threads are currently blocked waiting for this signal
(@code{sigwait()}), then the signal is delivered to the highest priority
thread waiting for this signal.
@item If any other threads are willing to accept delivery of the signal, then
the signal is delivered to the highest priority thread of this set. In the
event, multiple threads of the same priority are willing to accept this
signal, then priority is given first to ready threads, then to threads
blocked on calls which may be interrupted, and finally to threads blocked
on non-interruptible calls.
@item In the event the signal still can not be delivered, then it is left
pending. The first thread to unblock the signal (@code{sigprocmask()} or
@code{pthread_sigprocmask()}) or to wait for this signal
(@code{sigwait()}) will be the recipient of the signal.

@section Background
@subsection Thread Attributes
Thread attributes are utilized only at thread creation time.
@table @b
@item stack address
is the address of the optionally user specified stack area for this thread.
If this value is NULL, then RTEMS allocates the memory for the thread stack
from the RTEMS Workspace Area. Otherwise, this is the user specified
address for the memory to be used for the thread's stack. Each thread must
have a distinct stack area. Each processor family has different alignment
rules which should be followed.
@item stack size
is the minimum desired size for this thread's stack area.
If the size of this area as specified by the stack size attribute
is smaller than the minimum for this processor family and the stack
is not user specified, then RTEMS will automatically allocate a
stack of the minimum size for this processor family.
@item contention scope
specifies the scheduling contention scope. RTEMS only supports the
PTHREAD_SCOPE_PROCESS scheduling contention scope.
@item scheduling inheritance
specifies whether a user specified or the scheduling policy and
parameters of the currently executing thread are to be used. When
this is PTHREAD_INHERIT_SCHED, then the scheduling policy and
parameters of the currently executing thread are inherited by
the newly created thread.
@item scheduling policy and parameters
specify the manner in which the thread will contend for the processor.
The scheduling parameters are interpreted based on the specified policy.
All policies utilize the thread priority parameter.
