NAME
     winsysck - check which window system protocols are available

SYNOPSIS
     winsysck [ -va ]  [  -display  displaystring  ]  [  -timeout
     seconds ] protocol [...]

DESCRIPTION
     The winsysck command determines if the specified window sys-
     tem protocol is available to the user.  By default, the win-
     sysck 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 winsysck command.

     -a   Continue to check the  availability  of  the  specified
          protocols  even after determining that one or more pre-
          viously specified protocols are available.  This is not
          particularly useful without 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, separated 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 winsysck will time out.

KNOWN PROTOCOLS
     The following are known values for protocol.

     x11  Determines if a connection can be made  using  the  X11
          Window System protocol.

     news Determines if  a  connection  can  be  made  using  the
          Network-extensible Window System protocol.

     x11news
          Determines if connections can be made  to  an  X11/NeWS
          server.  In addition to being able to establish connec-
          tions using both the X11  Window  System  and  Network-
          extensible  Window System protocols, this requires that
          these two connections actually interact with  the  same
          window server.

User Commands                                         winsysck(1)



     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  prefer-
     ence 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 compa-
     tability enabled or to a SunView server.

BUGS
     None known.

DIAGNOSTICS
     Exit status is 0 if any protocols are available, 1  if  none
     are available, 2 for usage errors.
