- Type of return value(PSET,PREALI)
OUTPUT PARAMETERS
- INTEGER ERRIND
- Error indicator
- INTEGER EDFLAG
- Edge flag (POFF,PON)
- INTEGER EDTYPE
- Edge type
- RREAL EWIDTH
- Edge scale factor
- INTEGER CTYPE

PHIGS STATE
(PHOP, WSOP,*,*)
EFFECT
Returns the components contained in the specified edge representation of the
edge table in workstation WKID's workstation state list. If the
data is available, error indicator is returned as 0.
If the inquired information is available, the error indicator is returned as 0
and values are returned in the output parameters.
If the specified edge index is not present in the edge bundle table, and the
specified type of returned value is REALIZED, the representation for edge index
1 is returned.
If the inquired information is not available, the values returned in the output
parameters are implementation dependent and the error indicator is set to one
of the following error numbers to indicate the reason for non-availability:
ERRORS
- 3
Ignoring function, function requires state (PHOP, WSOP,*,*)
- 54
- Ignoring function, the specified workstation is not open
- 59
- Ignoring function, the specified workstation does not have output
capability (i.e. the workstation category is neither OUTPUT, OUTIN, nor MO)
- 100
- Ignoring function, the bundle index value is less than one
- 101
- Ignoring function, the specified representation has not been definded
