Description

PQIF queries the workstation description table and returns values for the following:

•List of available interior styles

•Total number of available hatch styles

•List of available hatch styles

•Total number of available hatch styles

•Number of predefined interior indexes

The value of the number of available hatch styles has the following interpretations:

Value      Result
Positive   The list of available hatch styles contains all
           registered hatch styles.
Negative   Two conditions apply:
 
           - Digital PHIGS derives the implementation-specific hatch styles
             directly from the value and the hatch style aspect.
           - The list of available hatch styles contains the registered
             hatch styles supported, the number of which is the absolute
             value of the number of available hatch styles.

The application must provide the space for the list of hatch styles.  The application passes the address of the list, an array of integers, in the ints field of the hatch_styles field of the facilities argument, and passes the size of the list in the num_elem argument.  Digital PHIGS returns the number of elements written in the list in the num_ints field of the hatch_styles field of the facilities argument.
