How to know there are multiple instances inside application itself,not through ssh
hi,
As you know, in Windows Programming, in WinMain method you will give n argument which you can know if this is another instance of the application or just the fresh execution.
How this functionality can be achieved in Linux application? Most of suggestions i have seen here in threads are done through ssh and shell scripting not inside application itself.
Regards,
Behzad

I have built this Solaris 10 server, uses NIS. When the server starts up, two instances of ypbind start. This prevents the server from binding to any domain. The SMF in turn prevents any other network services (sshd and the like) from starting up.

xtappcreateshell
XtAppCreateShell(3) XT FUNCTIONS XtAppCreateShell(3)
NAME
XtAppCreateShell, XtVaAppCreateShell - create top-level widget instance
SYNTAX
Widget XtAppCreateShell(String application_name, String application_class, WidgetClass widget_class, Display *display, ArgList args, Cardi-
nal num_args);
Widget XtVaAppCreateShell(String application_name, String application_class, WidgetClass widget_class, Display *display, ...);
ARGUMENTS
application_name
Specifies the name of the application instance.
application_class
Specifies the class name of this application.
widget_class
Specifies the widget class that the application top-level widget should be.
display Specifies the display from which to get the resources.
args Specifies the argument list from which to get the resources.
num_args Specifies the number of arguments in the argument list.
... Specifies the variable argument list from which to get the resources.
DESCRIPTION
The XtAppCreateShell function saves the specified application name and application class for qualifying all widget resource specifiers.
The application name and application class are used as the left-most components in all widget resource names for this application. XtApp-
CreateShell should be used to create a new logical application within a program or to create a shell on another display. In the first
case, it allows the specification of a new root in the resource hierarchy. In the second case, it uses the resource database associated
with the other display.
Note that the widget returned by XtAppCreateShell has the WM_COMMAND property set for session managers (see Chapter 4).
