Description

pinq_param_surf_facs returns information on polynomial surface types and data. 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 types argument, and passes the size in the num_elem_appl_list argument. Digital PHIGS returns the number of elements written to the list in the num_ints field of the types argument.

Digital PHIGS Version 4.1 does not support this function.
