Description

pinq_model_clip_facs returns the list of supported modeling clipping operators. Digital PHIGS always returns operator 1 (replace) and 2 (intersect).

The application must provide the space used by the list. The application passes the address of the list, an array of integers, in the ints field of the ops argument, and passes the size in the num_elems_appl_list argument. Digital PHIGS returns the number of elements written to the list in the num_ints field of the ops argument.

Digital PHIGS Version 4.1 does not support this function.
