Appendix A: System Routines - Error Handling 455 ERD_dialog Declaration: BOOL ERD_dialog (SSHORT errno, BOOL bGoto) Category(ies): Error Handling Description: Looks up and displays text of error message for error number errno in a dialog box. This routine waits for the user to press N or ¸ to dismiss the dialog box. The error dialog box always displays an [ESC=CANCEL] button. Additionally, the [Enter=GOTO] button is displayed if bGoto is TRUE. This routine does not perform the actual transfer to the program editor if the user presses ¸. This routine is the core of the user interface to the system error handler. It is rarely necessary to call this routine directly. ER_throwVar is usually adequate to handle error conditions. Inputs: errno - Number of system error message. bGoto - TRUE means add [Enter=GOTO] button to dialog box. FALSE means omit the [Enter=GOTO] button. Outputs: Returns TRUE if the [Enter=GOTO] button is visible and the user pressed ¸. Otherwise returns FALSE. Assumptions: errno must be the number of a system error - do not use this routine to display application error messages. Side Effects: May cause heap compression. Availability: All versions of the TI-89 / TI-92 Plus. TI-89 / TI-92 Plus Differences: None See Also: ER_throwVar Example: ERD_dialog(ER_MEMORY, FALSE); /* display ERROR: MEMORY dialog box */ /* Execution returns here after user presses [ENTER] or [ESC] */ TI-89 / TI-92 Plus Developer Guide Not for Distribution Beta Version January 26, 2001
