# = QMP monitor control
##

##
# @qmp_capabilities:
#
# Enable QMP capabilities.
#
# Arguments:
#
# @enable: An optional list of QMPCapability values to enable.  The
#     client must not enable any capability that is not mentioned in
#     the QMP greeting message.  If the field is not provided, it
#     means no QMP capabilities will be enabled.  (since 2.12)
#
# Example:
#
# -> { "execute": "qmp_capabilities",
#      "arguments": { "enable": [ "oob" ] } }
# <- { "return": {} }
#
# Notes: This command is valid exactly when first connecting: it must
#     be issued before any other command will be accepted, and will
#     fail once the monitor is accepting other commands.  (see qemu
#     docs/interop/qmp-spec.rst)
#
#     The QMP client needs to explicitly enable QMP capabilities,
#     otherwise all the QMP capabilities will be turned off by
#     default.
#
# Since: 0.13

##
# @QMPCapability:
#
# Enumeration of capabilities to be advertised during initial client
# connection, used for agreeing on particular QMP extension behaviors.

# @oob: QMP ability to support out-of-band requests.  (Please refer to
#     qmp-spec.rst for more information on OOB)

# @VersionTriple:
#
# A three-part version number.

# @major: The major version number.

# @micro: The micro version number.

# Since: 2.4

##
# @VersionInfo:
#
# A description of QEMU's version.
#
# @qemu: The version of QEMU.  By current convention, a micro version
#     of 50 signifies a development branch.  A micro version greater
#     than or equal to 90 signifies a release candidate for the next
#     minor version.  A micro version of less than 50 signifies a
#     stable release.
#
# @package: QEMU will always set this field to an empty string.
#     Downstream versions of QEMU should set this to a non-empty
#     string.  The exact format depends on the downstream however it
#     highly recommended that a unique name is used.
#
# Since: 0.14

# @query-version:
#
# Returns the current version of QEMU.
#
# Returns: A @VersionInfo object describing the current version of
#     QEMU.

# Since: 0.14
#
# Example:
#

##
# @query-commands:
#
# Return a list of supported QMP commands by this server
#
# Returns: A list of @CommandInfo for all supported commands
#
# Since: 0.14
#
# Example:
#
# -> { "execute": "query-commands" }

# Note: This example has been shortened as the real response is too
#     long.

##
# @quit:
#
# This command will cause the QEMU process to exit gracefully.  While
# every attempt is made to send the QMP response before terminating,
# this is not guaranteed.  When using this interface, a premature EOF
# would not be unexpected.
#
# Since: 0.14

# Example:
#
# -> { "execute": "quit" }
# <- { "return": {} }
##

##
# @MonitorMode:
#
# An enumeration of monitor modes.
#
# @readline: HMP monitor (human-oriented command line interface)

# @control: QMP monitor (JSON-based machine interface)

# Since: 5.0

#
# Options to be used for adding a new monitor.

#     emulator, control in qemu-storage-daemon)
#
# @pretty: Enables pretty printing (QMP only)
#
# @chardev: Name of a character device to expose the monitor on

# Since: 5.0
