INQUIRE LIST OF INTERIOR INDICES(3P) — Kubota Pacfic Computer Inc. (29 February 1991)

NAME

INQUIRE LIST OF INTERIOR INDICES− inquire list of interior indices defined on a workstation

SYNOPSIS

C Syntax

void
pinq_list_int_inds ( ws, length, start, error_ind, indices, total_length )
Pintws;workstation identifier
Pintlength;length of application list
Pintstart;starting position
Pint∗error_ind;OUT error indicator
Pint_list∗indices;OUT list of interior indices
Pint∗total_length;OUT length of list in PHIGS

Required PHIGS Operating States

(PHOP, WSOP, ∗, ∗)

DESCRIPTION

Purpose

Use INQUIRE LIST OF INTERIOR INDICES to obtain a list of the currently defined interior indices on the specified workstation. The defined interior table indices are conceptually sparse: a PHIGS implementation could allow definition of n interior representations with arbitrary indices. However, interior indices are nonsparse in PEX-SI; the n interior representations necessarily have indices 1 through n.

C Input Parameters

wsThe workstation identifier of the workstation whose interior indices are to be returned.

lengthNumber of items for which the application has allocated memory in the output parameter indices. 0 can be specified, in order to get the total length of the list.

startStarting position in the list at which to begin the inquiry.

C Output Parameters

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

indicesA pointer to a Pint_list structure in which the system returns the portion of the list of currently defined interior indices, starting at the entry specified with start.

Pint_list is defined in phigs.h as follows:

typedef struct {
Pintnum_ints;/∗ number of Pints in list ∗/
Pint∗ints;/∗ list of integers ∗/

} Pint_list;

The pointer indices->ints must be initialized to an array of length Pint elements.

total_length
A pointer to an integer in which to return the total length of the list. This is the value required for length when all the items in the list are to be returned.

ERRORS

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

054Ignoring function, the specified workstation is not open

059Ignoring function, the specified workstation does not have output capability (in other words, the workstation category is neither OUTPUT, OUTIN, nor MO)
