XtAppWarning() XtAppWarning()
Name
XtAppWarning - call the low-level warning handler.
Synopsis
void XtAppWarning(app_context, message)
XtAppContext app_context;
String message;
Inputs
app_context
Specifies the application context.
message Specifies the warning message that is to be reported.
Description
XtAppWarning() passes its arguments to the installed low-level warning handler. On POSIX systems, the default handler is _XtDefaultWarn-
ing(). It prints the message to the stderr stream and returns.
Usage
To report fatal error messages and exit, use XtAppError() or XtAppErrorMsg(). To change the low-level warning handler, use XtAppSetWarn-
ingHandler().
XtAppWarning() calls the "low-level" warning handler. It is better to use XtAppWarningMsg() which calls the "high-level" warning handler.
The high-level handler looks up the warning message in a resource database and so allows for customization and internationalization of
warning messages.
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.
