DESCRIPTION

Purpose

Use INQUIRE HLHSR MODE to determine the current HLHSR (hidden line and hidden surface removal) mode from a specified workstation’s state list.

C Input Parameters

wsThe workstation identifier of the workstation whose state list is queried.

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 location in which the system returns the HLHSR update state. Pupdatest is one of the values PNOTPENDING (“Not Pending”) or PPENDING (“Pending”).

cur_mode
A pointer to a location in which the system returns the current HLHSR mode.

req_mode
A pointer to a location in which the system returns the requested HLHSR mode. The requested mode can differ from the current mode if the update state is PENDING.

FORTRAN Input Parameters

WKIDThe workstation identifier of the workstation whose state list is queried.

FORTRAN Output Parameters

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

HUPDThe HLHSR update state; one of the values PNPEND (“Not Pending”) or PPEND (“Pending”).

CHRM
The current HLHSR mode.

RHRM
The requested HLHSR mode. The requested mode can differ from the current mode if the update state is PENDING.

ERRORS

003Ignoring function, function requires state (PHOP, WSOP, ∗, ∗)

054Ignoring function, the specified workstation is not open

057Ignoring function, specified workstation is of category MI
