     INTEGER mode

INTEGER FLDFset_poly_nnodes (cell_set, poly_nnodes_array, size, mode)
     INTEGER cell_set(OIDSIZ)
     INTEGER poly_nnodes_array(*)
     INTEGER size
     INTEGER mode

Description

These routines get/set the nnodes array within a specified Polyhedron cell set

The FLDFget_poly_nnodes routine can be used for both getting and setting the poly_nnodes_list array. When setting with a "get" routine (mode = OM_GET_ARRAY_WR or OM_GET_ARRAY_RW), it returns an integer representing a pointer to an integer representing a pointer to a pre-allocated array, and the developer just needs to fill in the values.

If the cell set is a Polyhedron, this routine returns the array of integers each of them representing number of nodes (or nunber of sides) for each polygon. For example if your Polyhedron cell_set has 3 polys, triangle, quad and five-sided polygon, the poly_nnodes_array will look {3,4,5}. To set this array use FLDFset_poly_nnodes().

To access data array you will need to use ARRFoffset function described in Appendix D of Developers Reference.

Parameters

cell_set

The integer id of a cell set, as returned by the FLDFget_cell_set routine.

poly_nnodes_array_ptr

In FLDFget_poly_nnodes, poly_nnodes_array is the address of an integer representing a pointer to an array in which the list is returned. Call ARRfree() on this an integer representing a pointer when you are done using it. To access data array you will need to use ARRFoffset function described in the OM reference pages. On 64-bit platforms dims_ptr is actually an INTEGER*8.

poly_nnodes_array

In FLDFset_poly_nnodes, poly_nnodes_array is an integer representing a pointer to an array from which the list will be copied.

size

In FLDFget_poly_nnodes, size is an integer in which the size of the poly_nnodes_array is returned. In FLDFset_poly_nnodes, size is an integer that sets the size of the poly_nnodes_array.

"size" is the number of elements in the array irrespective of type. (It is usually defined as ncells * cell_nnodes.)

mode

An integer constant that establishes the access mode for the array subobject. Constants for the possible values are defined in avs/om.h as follows.
