NAME

set_traversal_depth − set maximum depth of display list traversal

SYNOPSIS

C Syntax:

void set_traversal_depth(fildes, depth)
int fildes, depth;

FORTRAN77 Syntax:

subroutine set_traversal_depth(fildes, depth)
integer*4 fildes, depth

Pascal Syntax:

procedure set_traversal_depth(fildes, depth:integer);

DESCRIPTION

Input Parameters

fildes Integer file descriptor returned by gopen when an I/O path to a graphics device is opened. 

depth Maximum depth of traversal

Discussion

Set_traversal_depth sets the maximum traversal depth for the specified graphics device. 

During traversal, if the depth of traversal would exceed the maximum for the display list, warning 1042 is generated and the call_segment, execute_segment, cond_call_segment or cond_execute_segment element causing the condition is not traversed. 

ERRORS

1 Graphics device is not initialized for this operation. 

20 Value out of range - negative depths not allowed. 

DEFAULTS

The default maximum traversal depth is 42.
