Sample Preprocessor Generated Include Files
Figures 2-10 through Figure 2-12 illustrate, respectively, the type,
variable, and externals include files that correspond to the modified
source file in Figure 2-9. Note that the preprocessor inserts the
following three C compiler directives to reference the include files:
#include "sqltype"
#include "sqlvar"
#include "sqlextn"
These three directives are always inserted into the static or global
declaration part of the program.
