ARGUMENTSapp_context_return
Specifies the application context.application_class
Specifies the class name of this application, which usually is the generic name for all instances of this application. options Specifies how to parse the command line for anyapplication-specific resources. The options argu-
ment is passed as a parameter to XrmParseCommand.For further information, see Xlib - C Language X
Interface.num_options
Specifies the number of entries in the options list.argc_in_out
Specifies a pointer to the number of command line parameters.argv_in_out
Specifies the command line parameters.fallback_resources
Specifies resource values to be used if the appli-
cation class resource file cannot be opened or read, or NULL. args Specifies the argument list to override any other resource specification for the created shell widget. X Version 11 Last change: libXt 1.0.8 1XT FUNCTIONS XtAppInitialize(3xt)
num_args Specifies the number of entries in the argument
list. ... Specifies the variable argument list to override any other resource specification for the created shell widget.DESCRIPTION
The XtAppInitialize function calls XtToolkitInitialize fol-
lowed by XtCreateApplicationContext, then calls XtOpen-
Display with display_string NULL and application_name NULL,
and finally calls XtAppCreateShell with application_name
NULL, widget_class applicationShellWidgetClass, and the
specified args and num_args and returns the created shell.
The modified argc and argv returned by XtDisplayInitializeare returned in argc_in_out and argv_in_out. If
app_context_return is not NULL, the created application con-
text is also returned. If the display specified by the com-
mand line cannot be opened, an error message is issued andXtAppInitialize terminates the application. If
fallback_resources is non-NULL, XtAppSetFallbackResources is
called with the value prior to calling XtOpenDisplay.XtAppInitialize and XtVaAppInitialize have been superceded
by XtOpenApplication and XtVaOpenApplication respectively.SEE ALSO
