Before using any other DBTools functions, you must call DBToolsInit. When you are finished using the DBTools DLL, you must call DBToolsFini.
The primary purpose of the DBToolsInit and DBToolsFini functions is to allow the DBTools DLL to load the SQL Anywhere language DLL. The language DLL contains localized versions of all error messages and prompts that DBTools uses internally. If DBToolsFini is not called, the reference count of the language DLL is not decremented and it will not be unloaded, so be careful to ensure there is a matched pair of DBToolsInit/DBToolsFini calls.
The following code fragment illustrates how to initialize and clean up DBTools:
// Declarations
a_dbtools_info info;
short ret;
//Initialize the a_dbtools_info structure
memset( &info, 0, sizeof( a_dbtools_info) );
info.errorrtn = (MSG_CALLBACK)MyErrorRtn;
// initialize DBTools
ret = DBToolsInit( &info );
if( ret != EXIT_OKAY ) {
// DLL initialization failed
...
}
// call some DBTools routines . . .
...
// cleanup the DBTools dll
DBToolsFini( &info );
