Hello,
i am using the sigaction function to handle the SIGCHLD signal.Is it possible to use a class member function as the handler function (the sa_handler member of the sigaction structure)?
The function's signature is:
void (*sa_handler)(int);so i don't think i can use a static member function... (2 Replies)

Hi,
I believe the next code is wrong:
class Egg {
Egg e;
int i;
Egg(int ii=0) : i(ii) {}
};
because you would end up with an endless definition (memory allocation) of Egg objects, thus int i.
Ok, so God Eckel proposes for a singleton:
class Egg {
static Egg e;
int... (5 Replies)

Hi all!
I am trying to register a device in an existing device class, but I am

I have the two class definition as follows.
class A { public: int a; };
class B : virtual public A{ };
The size of class A is shown as 4, and size of class B is shown as 16. Why is this effect ?. (2 Replies)
There is base class B, and two derived classes D1 and D2 derived from Base. Base class B, have two data members ( public or protected or private or if any). D1 should inherit both these data members, and D2 should be deriving only one member from Base class. Is this kind of design possible without... (1 Reply)
Hello All,
I am a learner in C++. I was testing my inheritance knowledge with following piece of code.
#include <iostream>
using namespace std;
class base
{
public :
void display()
{
cout << "In base display()" << endl;
}
void display(int k)

XConfigureEvent(3) XLIB FUNCTIONS XConfigureEvent(3)NAME
XConfigureEvent - ConfigureNotify event structure
STRUCTURES
The structure for ConfigureNotify events contains:
typedef struct {
int type; /* ConfigureNotify */
unsigned long serial; /* # of last request processed by server */
Bool send_event; /* true if this came from a SendEvent request */
Display *display; /* Display the event was read from */
Window event;
Window window;
int x, y;
int width, height;
int border_width;
Window above;
Bool override_redirect;
} XConfigureEvent;
When you receive this event, the structure members are set as follows.
The type member is set to the event type constant name that uniquely identifies it. For example, when the X server reports a GraphicsEx-
pose event to a client application, it sends an XGraphicsExposeEvent structure with the type member set to GraphicsExpose. The display
member is set to a pointer to the display the event was read on. The send_event member is set to True if the event came from a SendEvent
protocol request. The serial member is set from the serial number reported in the protocol but expanded from the 16-bit least-significant
bits to a full 32-bit value. The window member is set to the window that is most useful to toolkit dispatchers.
The event member is set either to the reconfigured window or to its parent, depending on whether StructureNotify or SubstructureNotify was
selected. The window member is set to the window whose size, position, border, and/or stacking order was changed.
The x and y members are set to the coordinates relative to the parent window's origin and indicate the position of the upper-left outside
corner of the window. The width and height members are set to the inside size of the window, not including the border. The border_width
member is set to the width of the window's border, in pixels.
The above member is set to the sibling window and is used for stacking operations. If the X server sets this member to None, the window
whose state was changed is on the bottom of the stack with respect to sibling windows. However, if this member is set to a sibling window,
the window whose state was changed is placed on top of this sibling window.
The override_redirect member is set to the override-redirect attribute of the window. Window manager clients normally should ignore this
window if the override_redirect member is True.
