ARGUMENTS

23       app_context_return
24                 Specifies the application context.
25
26       application_class
27                 Specifies the class name of this application, which usually
28                 is the generic name for all instances of this application.
29
30       options   Specifies how to parse the command line for any application-
31                 specific resources.  The options argument is passed as a
32                 parameter to XrmParseCommand.  For further information, see
33                 Xlib - C Language X Interface.
34
35       num_options
36                 Specifies the number of entries in the options list.
37
38       argc_in_out
39                 Specifies a pointer to the number of command line parameters.
40
41       argv_in_out
42                 Specifies the command line parameters.
43
44       fallback_resources
45                 Specifies resource values to be used if the application class
46                 resource file cannot be opened or read, or NULL.
47
48       args      Specifies the argument list to override any other resource
49                 specification for the created shell widget.
50
51       num_args  Specifies the number of entries in the argument list.
52
53       ...       Specifies the variable argument list to override any other
54                 resource specification for the created shell widget.

DESCRIPTION

57       The XtAppInitialize function calls XtToolkitInitialize followed by
58       XtCreateApplicationContext, then calls XtOpenDisplay with dis‐
59       play_string NULL and application_name NULL, and finally calls XtAppCre‐
60       ateShell with application_name NULL, widget_class applicationShellWid‐
61       getClass, and the specified args and num_args and returns the created
62       shell.  The modified argc and argv returned by XtDisplayInitialize are
63       returned in argc_in_out and argv_in_out. If app_context_return is not
64       NULL, the created application context is also returned.  If the display
65       specified by the command line cannot be opened, an error message is
66       issued and XtAppInitialize terminates the application.  If fall‐
67       back_resources is non-NULL, XtAppSetFallbackResources is called with
68       the value prior to calling XtOpenDisplay.
69
70       XtAppInitialize and XtVaAppInitialize have been superceded by XtOpenAp‐
71       plication and XtVaOpenApplication respectively.
