Specifies the application context.
Specifies the class name of
this application, which usually is the generic name for all instances of
this application.
Specifies how to parse the command line for any application-specific
resources. The options argument is passed as a parameter to XrmParseCommand.
For further information, see Xlib - C Language X Interface.
Specifies the
number of entries in the options list.
Specifies a pointer to the number
of command line parameters.
Specifies the command line parameters.
Specifies
resource values to be used if the application class resource file cannot
be opened or read, or NULL.
Specifies the argument list to override any
other resource specification for the created shell widget.
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.
The XtAppInitialize function calls XtToolkitInitialize
followed by XtCreateApplicationContext, then calls XtOpenDisplay
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 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 XtAppInitialize
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and XtVaAppInitialize have been superceded by XtOpenApplication and XtVaOpenApplication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.
