# cygserver.conf
#
# Contains configurable parameters for the cygserver.
#
# The format of this file is easy.  Lines beginning with a hash `#' are
# comments and ignored.  Lines consisting of only whitespaces are ignored.
# Any other line is a setting for cygserver.
# A setting consists of a name/value pair, separated by whitespace.
# Each line must only consist of one name/value pair.
# Lines must not be longer than 1023 characters.
#
# Some settings can be overridden by a command line switch.  If so, it's
# mentioned below.
#
# Settings which are commented out will use the default values.  These are
# mentioned below, too.

# kern.srv.msgqueues: Determines whether XSI Message Queue support should be
# started, "yes" (or "true", "y", "t", "1") or "no" (or "false", "n", "f", "0").
# These values are valid for all binary type options.
# Default is "yes".  Command line option -q, --no-msgqueues
#kern.srv.msgqueues yes

# started.  Default is "yes".  Command line option -s, --no-semaphores

# Default is "yes", if stderr is a tty, "no" otherwise.
# Command line option -e, --stderr or -E, --no-stderr.
#kern.log.stderr no

# kern.log.level: Logging level.  Valid values are 1 to 7 with a bigger
# value emitting more logging output.  Default level is 6.
# Command line option -l, --log-level.
#kern.log.level 6

# kern.log.debug: Determines whether debug output should be printed to stderr.
# Default is "no".  Command line option -d, --debug
#kern.log.debug no

# XSI message queue parameters.
#
# Each message is broken up and stored in segments that are msgssz bytes
# long.  For efficiency reasons, this should be a power of two.  Also,
# it doesn't make sense if it is less than 8 or greater than about 256.

# kern.ipc.msgseg: Maximum no. of message queue segments hold concurrently.
# Default: 2048, Min: 256, Max: 65535
#kern.ipc.msgseg 2048

# Default: 8, Min: 8, Max: 1024
#kern.ipc.msgssz 8

# kern.ipc.msgmnb: Maximum no. of bytes in a single message queue.

# Default: 60, Min: 1, Max: 1024

# kern.ipc.semmnu: Total no. of undo structures hold by server.
# Default: 30, Min: 1, Max: 1024
#kern.ipc.semmnu 30

# kern.ipc.semmsl: Maximum no. of semaphores per semaphore id.
# Default: 60, Min: 1, Max: 1024
#kern.ipc.semmsl 60

# kern.ipc.semopm: Maximum no. of operations per semop call.
# Default: 100, Min: 1, Max: 1024

# kern.ipc.semume: Maximum no. of undo entries per process.
# Default: 10, Min: 1, Max: 1024

#kern.ipc.semaem 16384

# XSI shared memory parameters

# kern.ipc.shmmaxpgs: Maximum pages available for XSI shared memory.
# Changing shmmaxpgs immediately affects setting SHMMAX.  The relation
# between shmmaxpgs and SHMMAX is:  SHMMAX = shmmaxpgs * getpagesize().
# Default: 8192, Min: 1, Max: 32767
#kern.ipc.shmmaxpgs 8192

# kern.ipc.shmmni: Maximum number of shared memory segments, system wide.
# Default: 192, Min: 1, Max: 32767

# kern.ipc.shmseg: Maximum number of shared memory segments per process.
# Default: 128, Min: 1, Max: 32767
#kern.ipc.shmseg 128

# kern.ipc.shm_allow_removed: Determines whether a process is allowed to
# attach to a shared memory segment (using the shmat call) after a successful
# call to shmctl(IPC_RMID).  This is a Linux-specific, and therefore
# non-portable feature.  Use with care.  Default is "no".
#kern.ipc.shm_allow_removed no
