authxapi_RegisterExitFunction Function

Valid on UNIX

The authxapi_RegisterExitFunction function registers an exit function for a specific event. Registration should be handled during program startup and shutdown, although it can be performed at any stage.

If the function succeeds, it returns 0. If it fails, it sets the global variable errno and returns one of the following error codes:

int authxapi_RegisterExitFunction (int event, PFSeosExitFunc user_func);

Example: Registering a User's Exit Function.

This example illustrates how you use the authxapi_RegisterExitFunction function to deny all login attempts for the user ismith.

/* Sample function to deny all login attempts of user 'jsmith' */
int MyExitFunc(void *exit_data, SEOS_EXITRES *res)
{
    SEOS_EXITLOGIN *login_data;

    login_data = (SEOS_EXITLOGIN *)exit_data;
    if (login_data‑>szUname != NULL)
    {
             if (strcmp(login_data‑>szUname, “jsmith”))
                 return 0;
             res‑>result = SEOS_EXITR_DENY;
    }
    return 0;
}

/* The function Access Control looks for on initialization */
/* of extension. */
int sample_RegisterExit(void)
{
    return authxapi_RegisterExitFunction(AUTHXAPI_EV_PRELOGIN,
                                         MyExitFunc);
}
