Description

pinq_hlhsr_mode_facs queries the workstation description table and returns the list of available HLHSR modes.

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 modes argument, and passes the size in the num_elem argument. Digital PHIGS returns the number of elements written to the list in the num_ints field of the modes argument.
