OSI/AS Programming Manual

Appendix D Using the APS Procedures in a
C Application Program
056783 Tandem Computers Incorporated D–1
Section 3 provides the TAL syntax for the APS procedures. You must observe the
following additional rules when calling the APS procedures from a program coded
in C.
The C external declarations for the current version of the APS procedures are in
the file CEXTDECS (the default volume and subvolume are $SYSTEM.ZOSIAS).
You must include CEXTDECS in your program, preferably before making any
calls to the procedures.
The C versions of the APS definitions, whose DDL equivalents are described in
Appendix A, are in the file ZAPSC (the default volume and subvolume are
$SYSTEM.ZOSIAS). You can use the #include directive to include them in your
C program.
In a C program, all references to the APS procedures and declarations must be in
uppercase.
All C modules that are going to be bound together must use the same version of
the Tandem C compiler, Clib, and LargeC.
For additional information on calling procedures in C, refer to the Tandem C Reference
Manual.
