NAME

INQUIRE DYNAMICS OF STRUCTURES − inquire the dynamics of structures for a workstation type

SYNOPSIS

C Syntax

void
pinq_dyns_structs ( type, error_ind, dynamics )
Pinttype;workstation type
Pint∗error_ind;OUT error indicator
Pdyns_structs∗dynamics;OUT structure dynamics

Required PHIGS Operating States

(PHOP, ∗, ∗, ∗)

DESCRIPTION

Purpose

Use INQUIRE DYNAMICS OF STRUCTURES to determine the dynamics of changes to structure contents and posting for a specified workstation type. 

The possible dynamic modification accepted values are: PDYN_IRGModification leads to an Implicit Regeneration.  PDYN_IMMModification is performed Immediately, without an implicit regeneration.  PDYN_CBSModification Can Be Simulated before an implicit regeneration is permitted. 

C Input Parameters

type
The workstation type whose capabilities are inquired.

C Output Parameters

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

dynamics
A pointer to a structure in which the system returns the dynamic modification accepted values for various structure manipulations.  Pdyns_structs is defined in phigs.h as follows:

typedef struct {
Pdyn_modcontent;/∗ structure content ∗/
Pdyn_modpost;/∗ post structure ∗/
Pdyn_modunpost;/∗ unpost structure ∗/
Pdyn_moddel;/∗ delete structure ∗/
Pdyn_modref;/∗ structure reference ∗/
} Pdyns_structs;

The Pdyn_mod enumeration holds the dynamic modification accepted value, one of the values PDYN_IRG, PDYN_IMM, or PDYN_CBS. 

ERRORS

002Ignoring function, function requires state (PHOP, ∗, ∗, ∗)

051Ignoring function, this information is not yet available for this workstation type; open a workstation of this type and use the specific workstation type

052Ignoring function, workstation type not recognized by the implementation

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

062Ignoring function, this information is not available for this MO workstation type
