CPU & Memory Calling c program from another c program
Hi All,

Probably this is a repeated question. My knowledge in this is limited and i got confused on all those materials i got in google search.
We use #include <> to include a predefined library like stdio.h
i saw somewhere that #include "" includes a man made module(another C program). IS this possible?

Let me make this simple
I have two files, say parent.c and child.c
child.c contains function definitions which is called from parent.c

My code:
parent.c
Code:
#include <stdio.h>

int main()
{
        int ret_option;
        ret_option = menu();
        return 0;
}

child.c

Code:
#include<stdio.h>
int menu();
int menu()
{

        int option;
        printf("\tWelcome to Address Search Engine\n");
        printf("-----------------------------------------\n");
        printf("1. Add\n2. Edit\n3. Delete\n4. Search\n0 for exit\n");
        printf("Enter your Selection : ");
        scanf("%d",&option);
        return (option);
}

What i need to do here is just display the menu on the screen.

Now how do I call this or include or link the two files ?


Thanks in advance
JS

xmcreatepopupmenu

XmCreatePopupMenu(library call) 										   XmCreatePopupMenu(library call)

NAME

       XmCreatePopupMenu -- A RowColumn widget convenience creation function

SYNOPSIS

       #include <Xm/RowColumn.h>
       Widget XmCreatePopupMenu(
       Widget parent,
       String name,
       ArgList arglist,
       Cardinal argcount);

DESCRIPTION

       XmCreatePopupMenu  creates  an instance of a RowColumn widget of type XmMENU_POPUP and returns the associated widget ID. When this function
       is used to create the Popup menu pane, a MenuShell widget is automatically created as the parent of the	menu  pane.   The  parent  of  the
       MenuShell widget is the widget indicated by the parent parameter.

       XmCreatePopupMenu is provided as a convenience function for creating RowColumn widgets configured to operate as Popup menu panes and is not
       implemented as a separate widget class.

       The PopupMenu is used as the first menu pane within a PopupMenu system; all other menu panes are of the Pulldown type. A  Popup	menu  pane
       displays a 3-D shadow, unless the feature is disabled by the application.  The shadow appears around the edge of the menu pane.

       The  Popup  menu pane must be created as the child of a MenuShell widget in order to function properly when it is incorporated into a menu.
       If the application uses this convenience function for creating a Popup menu pane, the MenuShell is automatically created as the real parent
       of  the	menu pane.  If the application does not use this convenience function to create the RowColumn to function as a Popup menu pane, it
       is the application's responsibility to create the MenuShell widget.

       To access the PopupMenu, the application must first position the widget using the XmMenuPosition function and then manage it  using  XtMan-
       ageChild.

       parent	 Specifies the parent widget ID

       name	 Specifies the name of the created widget

       arglist	 Specifies the argument list

       argcount  Specifies the number of attribute/value pairs in the argument list (arglist)

       Popup  menu  panes  support tear-off capabilities for tear-off menus through XmRowColumn resources.  For a complete definition of RowColumn
       and its associated resources, see XmRowColumn(3).

RETURN

       Returns the RowColumn widget ID.
