# @InetSocketAddress:
#
# Captures a socket address or address range in the Internet namespace.
#
# @numeric: true if the host/port are guaranteed to be numeric,
#           false if name resolution should be attempted. Defaults to false.
#           (Since 2.9)
#
# @to: If present, this is range of possible addresses, with port
#      between @port and @to.
#
# @ipv4: whether to accept IPv4 addresses, default try both IPv4 and IPv6
#
# @ipv6: whether to accept IPv6 addresses, default try both IPv4 and IPv6

# @VsockSocketAddress:
#
# Captures a socket address in the vsock namespace.

# @port: port
#
# Note: string types are used to allow for possible future hostname or
# service resolution support.
#
# Since: 2.8

##
# @SocketAddressLegacy:
#
# Captures the address of a socket, which could also be a named file descriptor
#
# Note: This type is deprecated in favor of SocketAddress.  The
# difference between SocketAddressLegacy and SocketAddress is that the
# latter is a flat union rather than a simple union. Flat is nicer
# because it avoids nesting on the wire, i.e. that form has fewer {}.

# Since: 1.3

# @SocketAddressType:
#
# Available SocketAddress types
#
# @inet:  Internet address
#
# @unix:  Unix domain socket
#
# @vsock: VMCI address
#
# @fd: decimal is for file descriptor number, otherwise a file descriptor name.
#      Named file descriptors are permitted in monitor commands, in combination
#      with the 'getfd' command. Decimal file descriptors are permitted at
#      startup or other contexts where no monitor context is active.

# Since: 2.9
