GPQHF - Inquire Hatch Facilities

GPQHF (wstype, errind, format, maxlen, npred, available)

Note:

This subroutine is a Workstation Description Table (WDT) inquiry. For an overview, see "WDT Inquiries"

Purpose

Use GPQHF to inquire the hatch facilities for the specified workstation type.

If the information is available, then the graPHIGS API sets the error indicator to zero and returns the values in the output parameter. If the output parameter available, is set to 1, then the values returned in the other output parameters are unpredictable. If the inquired information is unavailable, then the error indicator (errind) contains the error number indicating the reason, and the values returned in the output parameter are unpredictable.

Parameters

wstype -- specified by user, 8-byte character string

Workstation type.

errind -- returned by the graPHIGS API, fullword integer

Error indicator. If the error indicator is zero, the request has been completed. Otherwise, one of the following errors exists:

23: SPECIFIED WORKSTATION TYPE DOES NOT EXIST
35: WORKSTATION HAS ONLY INPUT CAPABILITIES
548: SPECIFIED WORKSTATION TYPE CANNOT BE LOADED

format -- returned by the graPHIGS API, fullword integer

Hatch definition format (1=BIT_ARRAY )

maxlen -- returned by the graPHIGS API, fullword integer

Maximum length of hatch definition data.

npred -- returned by the graPHIGS API, fullword integer

Number of predefined hatch patterns.

available -- returned by the graPHIGS API, fullword integer

Availability of the Set Hatch Representation (GPHR) subroutine or Inquire Hatch Representation (GPQHR) subroutine subroutine (1=NOT_AVAILABLE, 2=BOTH_AVAILABLE, 3=INQUIRE_ONLY_AVAILABLE, 4=SET_ONLY_AVAILABLE )

Error Codes

None
