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

NAME

INQUIRE LIST OF TEXT INDICES− inquire list of text indices defined on a workstation

SYNOPSIS

C Syntax

void
pinq_list_text_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 text indices
Pint∗total_length;OUT length of list in PHIGS

Required PHIGS Operating States

(PHOP, WSOP, ∗, ∗)

DESCRIPTION

Purpose

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

C Input Parameters

wsThe workstation identifier of the workstation whose text 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 text indices, starting at the entry specified with start.

Pint_list is defined in phigs.h as follows:

typedef struct {
Pint num_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 if 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)
