Initializing and finalizing the DBTools library

Before using any other DBTools functions, you must call DBToolsInit. When you are finished using the DBTools library, you must call DBToolsFini.

The primary purpose of the DBToolsInit and DBToolsFini functions is to allow the DBTools library to load and unload the SQL Anywhere message library. The message library contains localized versions of all error messages and prompts that DBTools uses internally. If DBToolsFini is not called, the reference count of the messages library 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 finalize 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 the DBTools library
ret = DBToolsInit( &info );
if( ret != EXIT_OKAY ) {
    // library initialization failed
    ...
}
// call some DBTools routines ...
...
// finalize the DBTools library
DBToolsFini( &info );
