winsysck(1) General Commands Manual winsysck(1) NAME winsysck - check which window system protocols are available SYNOPSIS /usr/bin/winsysck [ -va ] [ -display displaystring ] [ -timeout seconds ] protocol [...] DESCRIPTION The winsysck command determines if the specified window system protocol is available to the user. By default, the winsysck command exits as soon as the first available protocol is found, although this behaviour can be modified by the -a option (see below). OPTIONS The following options can be used to modify the behaviour of the win- sysck command. -a Continue to check the availability of the specified protocols even after determining that one or more previously specified protocols are available. This is not particularly useful with- out the -v option (see below). -v Print the name of the first available protocol on the standard output. When combined with the -a option (see above), print the name of all available protocols on the standard output, sepa- rated by newlines. -display displaystring Use the display displaystring when trying to determine if the x11 protocol is available. -timeout seconds The timeout option sets the number of seconds before the win- sysck will time out. KNOWN PROTOCOLS The following are known values for protocol. x11 Determines if a connection can be made using the X11 Window Sys- tem protocol. news Determines if a connection can be made using the Network-exten- sible Window System protocol. x11news Determines if connections can be made to an X11/NeWS server. In addition to being able to establish connections using both the X11 Window System and Network-extensible Window System proto- cols, this requires that these two connections actually interact with the same window server. sunview Determines if connections can be made using the SunView Window System protocol. EXAMPLES Determine if an X11 Window System connection can be made: example% if winsysck x11 ; then ... Determine if an X11 Window System connection can be made to the display "displayhost:0.0": example% if winsysck -display displayhost:0.0 x11 ; then ... Print the known protocols which are available: example% winsysck -v -a x11 news x11news sunview Print which window system should be used, given the preference for NeWS over SunView, and X11/NeWS over NeWS: example% winsysck -v x11news news sunview SEE ALSO Xserver(1) LIMITATIONS There is no way to determine whether a SunView connection is actually connected to an X11/NeWS server with SunView compatibility enabled or to a SunView server. winsysck assumes that no system running this version of Oracle Solaris could be running SunView, NeWS, or X11/NeWS, so doesn't bother checking for anything but X11. BUGS None known. DIAGNOSTICS Exit status is 0 if any protocols are available, 1 if none are avail- able, 2 for usage errors.
