Syntax

[C/C++:]
void gEnqPolygonWindowList(int list[], int n, int *count);

[F90:]
subroutine gEnqPolygonWindowList(list, n, count)

integer, intent(in) :: n
integer, intent(out) :: list(*),count

Arguments

list
Integer array returning selected polygon identifiers

n
Number of polygon identifiers to return

= 0,	Nothing returned in list

count
Number of polygon identifiers in last call to gSetPolygonWindow()

Description

The routine gEnqPolygonWindowList() returns a list of polygon identifiers that are currently selected for polygon windowing. The polygons are selected using the routine gSetPolygonWindow().

The array list should be declared of length n, and no more than that number of identifiers are returned. count returns the actual number of polygon identifiers selected with gSetPolygonWindow() even if this number is greater then n. If count = 0 then polygon windowing is not being used.

If n is less than or equal to zero, no numbers are returned in list. If n is less than zero, a warning message is output.
