7-4 Integrating SCRIPTS Programs into “C” Language Drivers
Figure 7.3 SCRIPTS Table Declaration
7.1.2.2 Creating Table Indirect Entry Offsets
The “C” code example in Figure 7.4 sets up a table that can be used with
the table indirect addressing mode. Each entry in the table is a pair of
32-bit values. These entries reference the same buffers as the SCRIPTS
code examples above. For more illustration on the relationship between
these pieces of code, refer to
Section 7.1.2, “Table Indirect Operations.”
For this SCRIPTS program to work correctly, the table must start on a
Dword boundary and the offset labels must be in the same order as in
the SCRIPTS table declaration.
