PHIGS STATE

EFFECT

If the inquired information is available, the error indicator is returned as 0 and values are returned in the output parameters.

If the specified depth cue index is not present in the depth cue table, and the specified type of returned value is REALIZED, the representation for depth cue 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)

101

Ignoring function, the specified representation has not been definded

119

Ignoring function, the specified depth cue mode is not available on the workstation
