Declaration Files

The declaration files provide definitions for the GPI library procedures and for data

types that are used as parameters to GPI procedure calls. The name and contents of each

declaration file are listed in Table 2-7

Data Declaration Files

The data declaration files define data types used as parameters to GPI procedure calls.

GPIDEFS and GPIDEFSH files are TAL and C versions of that file, respectively.

Within these files, each of the various data types is grouped into a separate section.

Table 2-8

lists each section and provides a brief description of its contents.
