    } pets;
} Pstroke_data;

Because this function returns information on the default stroke data (PET 1), the data structures for the other PETs have been omitted.

Description

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

•Maximum stroke buffer size

•List of available prompt and echo types

•Default echo area in device coordinates

•Default stroke data record
