XtOpenApplication(3) XT FUNCTIONS XtOpenApplication(3) NAME XtOpenApplication, XtVaOpenApplication - initialize, open, or close a dis- play SYNTAX #include <X11/Intrinsic.h> Widget XtOpenApplication(XtAppContext *app_context_return, const char *ap- plication_class, XrmOptionDescRec *options, Cardinal num_options, int *argc_in_out, char **argv_in_out, String *fallback_resources, WidgetClass widget_class, ArgList args, Cardinal num_args); Widget XtVaOpenApplication(XtAppContext *app_context_return, const char *application_class, XrmOptionDescRec *options, Cardinal num_options, int *argc_in_out, char **argv_in_out, String *fallback_resources, WidgetClass widget_class, ...); ARGUMENTS app_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 any application-spe- cific resources. The options argument is passed as a parameter to XrmParseCommand. For further information, see Xlib - C Lan- guage 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 application class re- source file cannot be opened or read, or NULL. widget_class Specifies the widget class of the shell to be created. args Specifies the argument list to override any other resource speci- fication for the created shell widget. num_args Specifies the number of entries in the argument list. ... Specifies the variable argument list to override any other re- source specification for the created shell widget. DESCRIPTION The XtOpenApplication function calls XtToolkitInitialize followed by XtCre- ateApplicationContext, then calls XtOpenDisplay with display_string NULL and application_name NULL, and finally calls XtAppCreateShell with applica- tion_name NULL, the specified widget_class, and the specified args and num_args and returns the created shell. The modified argc and argv re- turned by XtDisplayInitialize are returned in argc_in_out and argv_in_out. If app_context_return is not NULL, the created application context is also returned. If the display specified by the command line cannot be opened, an error message is issued and XtOpenApplication terminates the applica- tion. If fallback_resources is non-NULL, XtAppSetFallbackResources is called with the value prior to calling XtOpenDisplay. XtAppInitialize and XtVaAppInitialize have been superseded by XtOpen- Application and XtVaOpenApplication respectively.
