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 subroutine 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.

stateA pointer to a Pdefupdatest structure in which the system returns the default display update state for the specified workstation type. Pdefupdatest is defined in phigs.h as:

typedef struct {
Pdefmodedef_mode;/∗ deferral mode ∗/
Pmodmod_mode;/∗ modification mode ∗/
} Pdefupdatest;

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

typedef enum {
PASAP,As soon as possible
PBNIG,Before the next interaction globally
PBNIL,Before the next interaction locally
PASTI,At some time
PWAITWhen the application requests it
} Pdefmode;

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

typedef enum {
PNIVE,No immediate visual effects mandated
PUWOR,Update without regeneration
PUQUMUse quick update methods
} Pmod;

FORTRAN Input Parameters

WTYPE
Type of workstation.

FORTRAN Output Parameters

ERRIND
The error number of any error detected by this function.

DEFMOD
The default deferral mode for the specified workstation type. Deferral mode values are enumerated values defined in phigs77.h as:

0PASAP,As soon as possible
1PBNIG,Before the next interaction globally
2PBNIL,Before the next interaction locally
3PASTI,At some time
4PWAITDWhen the application requests it

MODMOD
The default modification mode for the specified workstation type. Modification mode values are enumerated values defined in phigs77.h as:

0PNIVE,No immediate visual effects mandated
1PUWOR,Update without regeneration
2PUQUMUse quick update methods

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

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