Required PHIGS Operating States

(PHOP, ∗, ∗, ∗)

DESCRIPTION

Purpose

Use INQUIRE DEFAULT DISPLAY STATE to determine the default display update state for a specified workstation type. The display update state consists of a deferral mode and a modification mode.

See the description of the function SET DISPLAY UPDATE STATE for information on the meaning of these modes.

C Input Parameters

type
Type of workstation.

C Output Parameters

error_ind
A pointer to the location to store the error number of any error detected by this function.

def_mode
The deferral mode, def_mode, is defined in phigs.h as:

typedef enum {
PDEFER_ASAP, As Soon As Possible
PDEFER_BNIG, Before the Next Interaction Globally
PDEFER_BNIL,Before the Next Interaction Locally
PDEFER_ASTI,At Some Time
PDEFER_WAITWhen the Application Requests It
} Pdefer_mode;

mod_mode
The modification mode, mod_mode, is defined in phigs.h as:

typedef enum {
PMODE_NIVE,No immediate visual effects mandated
PMODE_UWOR, Update without regeneration
PMODE_UQUMUse quick update methods
} Pmod_mode;

ERRORS

002Ignoring function, function requires state (PHOP, ∗, ∗, ∗)

052Ignoring function, workstation type not recognized by the implementation

051Ignoring function, this information is not yet available for this workstation type; open a workstation of this type and use the specific workstation type

059Ignoring function, the specified workstation does not have output capability (i.e. the workstation category in neither OUTPUT, OUTIN, nor MO)

062Ignoring function, this information is not available for this MO workstation type
