XtAppError() XtAppError()
Name
XtAppError - call the low-level error handler.
Synopsis
void XtAppError(app_context, message)
XtAppContext app_context;
String message;
Inputs
app_context
Specifies the application context.
message Specifies the error message to be reported.
Returns
XtAppError() terminates the application and does not return.
Description
XtAppError() passes its arguments to the installed low-level error handler. On POSIX systems, the default handler is _XtDefaultError().
It prints the message to the stderr stream and calls exit().
Usage
To report non-fatal error messages or warnings without exiting, use XtAppWarning() or XtAppWarningMsg(). To change the low-level error
handler, use XtAppSetErrorHandler().
XtAppError() calls the "low-level" error handler. It is better to use XtAppErrorMsg() which calls the "high-level" error handler. The
high-level handler looks up the error message in a resource database and so allows for customization and internationalization of error mes-
sages.
Although the Intrinsics interface allows separate error and warning handlers for each application context, most implementations will sup-
port only a single set of handlers. When a new handler is installed, it will be used in all application contexts.
