Hence, FIRST_MODULE should be defined at the very top of the first module to be compiled. Ordinarily, the basic database system, codas3\source\db*.c would be compiled and placed in a library. Programs using these subroutines to build and access databases DO NOT NEED these global variables. In other words, this file (dbglo.h), is needed only for compiling the core database subroutines. The strategy for declaration of global variables may be compiler- dependent. If in doubt, check your compiler manual and make adjustments as needed. */ #ifndef dbglo_included #define dbglo_included #ifndef dbext_included #include "dbext.h" /* UBYTE, CHAR, ... */ #endif #ifndef dbinc_included #include "dbinc.h" /* DATABASE_TYPE, MAX_OPEN_DATABASES */ #endif #define MS_SIZE 18 #ifdef FIRST_MODULE #undef FIRST_MODULE DATABASE_TYPE *db;
