The graPHIGS Programming Interface : Subroutine Reference
GPQMTF - Inquire Marker Type Facilities
| GPQMTF
(wstype,
errind,
format,
maxlen,
npred,
available) |
Note:
This subroutine is a Workstation Description Table (WDT)
inquiry.
For an overview, see
"WDT Inquiries"
Purpose
Use
GPQMTF to inquire the marker pattern
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 a
value of one, 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
Marker definition format
(1=VECTOR
)
maxlen -- returned by the graPHIGS API, fullword integer
Maximum length of marker definition data.
npred -- returned by the graPHIGS API, fullword integer
Number of predefined marker pattern.
available -- returned by the graPHIGS API, fullword integer
Availability of the Set Marker Type Representation
(GPMTR) subroutine
and Inquire Marker Type Representation
(GPQMTR) subroutine
(1=NOT_AVAILABLE, 2=BOTH_AVAILABLE, 3=INQUIRE_ONLY_AVAILABLE, 4=SET_ONLY_AVAILABLE
)
