Application I/O Functions

E.1 Introduction

This appendix contains the specifications of the application I/O (applio) functions which can be implemented to replace or extend the normal part file handling functions in the Frustrum. These functions are used during input and output of transmit files with ‘application i/o’ format.

There is further information on the use of the application I/O functions in Section 2.3.2, “Application I/O”.

E.1.1 Registering the application I/O functions

The application I/O functions must be registered with Parasolid by calling the PK function PK_SESSION_register_applio_2, before the Parasolid session is started.

E.1.2 Application I/O functions that can be registered

This section lists the application I/O functions that you can register during a Parasolid session.

Note: In the following list, the function names given are purely nominal, as the functions are registered by the call to PK_SESSION_register_applio_2.
