dbwinexit (Windows only)

Informs DB-Library that the Windows application is about to exit.

Syntax

void dbwinexit ( void );

Remarks

DB-Library for Windows maintains information about each application that has referenced it. DB-Library creates the information when a library application calls dbinit; it does this to prevent conflicts between applications that use DB-Library concurrently. In order for DB-Library to release this information, the application must call dbwinexit just before it exits. You should put the call to dbwinexit within the message handling code for the WM_DESTROY message. For example:

case WM_DESTROY:
    dbwinexit();
    break;

This call releases the memory DB-Library allocated to keep track of this application and makes that memory available to other applications.

Important Once your application has called dbwinexit, it cannot call any other DB-Library function. If you have called dbwinexit and then need to issue one or more DB-Library calls, you must call dbinit again to re-register your application.
