We recently had use for knowing whether a particular PHIGS
workstation was currently open or not, and we located the
INQUIRE WORKSTATION STATE VALUE routine in the SunPHIGS 1.1
manual (p 675). However, there appears to be no way to
tell this routine which workstation we are asking about,
as there is no workstation id argument in the argument list,
only the argument for the returned state of some workstation.
E.g.
In C, the call is: pinqwsst( ws_state )
Pwsstate *ws_state;
In fortran, the call is: call pqwkst( wksta )
integer wksta
How do we use this routine to inquire about a specific
workstation?
Thanks,

INQUIRE WORKSTATION STATE VALUE returns whether or not the PHIGS state is WSOP. If you want to know if a particular workstation is open you should use an inquiry which will return an error if the specified workstation is not open. INQUIRE WORKSTATION CONNECTION AND TYPE is just such an inquiry. It should only return an error if there are no workstations open ( error #3 ) or if the specified workstation is not open ( error #54 ) -Jan "YON" Hardenbergh - jch@stardent.com uunet!stardent!jch Stardent Computer, Inc., 95 Wells Ave., Newton, MA 02159 (617)964-6228x261 -- -Jan "YON" Hardenbergh - jch@stardent.com uunet!stardent!jch Stardent Computer, Inc., 95 Wells Ave., Newton, MA 02159 (617)964-6228x261

[The page numbers I give reference the standard ISO/IEC 9592-1:1988(E)] PHIGS has several operating states. These are: PHIGS: Open/Closed Workstatiob: Open/Closed Archive File: Open/Closed Structure: Open/Closed The INQUIRE WORKSTATION STATE VALUE tells you whether or not the application currently has at least one workstation open (pg. 107). Each workstation has in its state list whether or not it is open or closed (pg. 68). What you probably want is a list of all open workstations which you can then search to find the workstation you're looking for: (pg. 235) INQUIRE SET OF OPEN WORKSTATIONS (PHOP, *, *, *) Parameters: Out Error Indicator Integer Out Set of Open Workstations List(Workstation Identifiers) This should return to you a list of the ID's of the workstations that are open by this application. -- Rich Rich Thomson thomson@cs.utah.edu {bellcore,hplabs,uunet}!utah-cs!thomson ``If everybody is thinking the same thing, is anybody thinking?'' --Bob Johnson
