Module #09.01.02.01 : Workstation errors handled by user

All PVT documentation can be found under PHIGS Validation Tests - Overview. You may also return to the hierarchical table of topics covered by the PVT. For an explanation of the format of the individual module documentation, please see section 2.5 of the User's Guide.


DESCRIPTION: This module tests that the functions related to workstation
generate the specified workstation error messages if they are executed in
incorrect conditions. The error is handled by a user defined error handling
subroutine. Also, this module tests the requirement that no side effects
are generated.

SEMANTIC REQUIREMENTS:


SR1.  If function <open workstation> is called, and the specified
connection identifier is not recognized by the implementation, then
error 50 or 55 is generated and the function is ignored.
#F 3
#D 1.2 8.1
#S 4.12/109/6
#T 
SR2.  If function <open workstation> is called, and the specified
workstation type is not recongnized by the implementation, then error
52 or 55 is generated and the function is ignored.
#F 3
#D 1.2 2.2 8.1
#S 4.12/109/6
#T P01/1 P01/2 
SR3.  If function <open workstation> is called, and the specified
workstation identifier already is in use, then error 53 is generated
and the function is ignored.
#F 3
#D 1.2 4.1.1 5.1 8.1
#S 4.12/109/6
#T P02/1 P02/2 
SR4.   If functions <close workstation>-<messages>, <set polyline

pick filter>-<sample string>, <flush device events>, <write item to metafile>-
<read item from metafile> are called , and the specified workstation is not
open, then error 54 or 3 is generated and the function is ignored.

<set pick mode>, <request stroke>, <request pick>, <sample pick> are called,
and the specified workstation is not of category OUTIN, then error 60 is
generated and the function is ignored.
