Re: [Dev-C++] Memory

[Per W. <pw...@ia...>]

For just about all OS, the memory allocated by malloc and new will be
released by the OS uppon program termination, i.e. you don't need to
release it.

However, there are a number of reasons for releasing it anyway:
- A debug build may then check for unreleased memory, and can inform you
about any memory leaks. A single variable living through the whole program
isn't considered a leak. However a buffer that the application
should allocate/reallocate regularly during normal operation, and that
isn't deallocated is a leak, i.e. while the same instance of the program
continues running, the needed memory continues to grow.

- When programming in C++, the destructor run when you release your class
objects might have other side effects. It might change current mouse
cursor, perform flush on file system, remove temporary files, close down a
non-standard graphics mode etc.

- If all allocated memory gets released when not needed anymore, it is
easier to look at the code and determine the useful lifespan of the
different variables. There isn't any use to add code to keep a structure
up to date, if nobody will ever check the values of the structure anymore.

- To support code reuse. What might be a standalone program now, might
very well become a sub-module in a larger project tomorrow, and then you
don't want to have to pick the code to pieces to get it working.

I have probably missed a couple of really important reasons but yes, i'd
suggest that you try and release all malloc/calloc/new memory before
ending the program, or preferably as soon as you know that you will not
need the information anymore.

Re: [Dev-C++] Memory

[Robson B. <rob...@su...>]

Thanks for input, people!

Re: [Dev-C++] Memory

[Daniel G. <sp...@ho...>]

For C++ you must delete any objects you create with the new operator. 
Variables created normally will be destroyed when they go out of scope.

So
int main(int argc, char** argv)
{
   int SomeInt = 0;

   return 0;
}
// SomeInt has been destroyed.

or try
int main(int argc, char** argv)
{
   {
      // The { doesn;t do anything except limit
      // the scope of everything within.
      int SomeInt = 0;

   } // someInt now destroyed.

   return 0;
}


but if you do
MyClass* Ptr;   // Ptr can point to a MyClass object
Ptr = new Myclass;

//...

delete Ptr;        // Delete the object and free the memory.


This is because with 'new' you allocate memory at run time, not at compile 
time.

Re: [Dev-C++] Memory

[<rol...@mi...>]

- variables allocated in stack must not (should not ) be deleted
- variables allocated with new och malloc must be free'd

void main( void )
{
      int  a ;  // allocated on stack - no delete!
      int* b = new int ;  // allocated with new - do delete!

     a = 10 ;
     *b = 10 ;
    ...
    ...
    delete b ;  // free b!
}

[Dev-C++] Memory

[Robson B. <rob...@su...>]

Hi coders,

I have a question that does not want to shut up! When i code a program, do i
have to delete all variables before exiting the main function or does the
operating system cares of free all the memory allocated? If i do not delete
the variables before main function and use the program several times, may it
cause the system memory to be unavailble?

Any input welcome!

Thanks!

By the way guys and girls, did you know that in C++98 you can do:


#include <iostream>

int main()
{
 int x=1, y=2;
 
 if(x>y or x*y==2)
  std::cout<<"Beep beep\n";
  

  y=y bitand x;
  
  x and_eq y;

}



That is to use keywords instead of || etc symbols?

Re: [Dev-C++] need some explanation

[Luigi S. <gi...@li...>]

OK, guys, it's clear now.

I'm a bit less concerned, because I do not use the notation 
   char s[3] = "abc";
but have learned to use one of the safer ones: 
   char *s = "abc";
or
   char s[] = "abc"; 

That is the reason why the piece of code seemed correct to me.

Of course the following is correct both in C89 and C++98, isn't it?
   char s[3] = { 'a', 'b', 'c' };

Re: [Dev-C++] How to force C linkage?

[jo m. <non...@ho...>]

I don't know what Lua40 or Lua50 are, but try compiling in C++ mode and put 
your C declarations inside "alternate C linkage" like this:

extern "C"
{
   #include "Myheader.h"
}

Hope this helps.

RES: RES: [Dev-C++] Does anyone know how to use GtkGlext in Dev-C++?

[Daniel K. O. <dan...@ya...>]

Well, I use a template file like this (`Templates\Gtk.template'):
=========================
[Template]
ver=1
Name=Gtk
Icon=Gtk.ico
Description=Create a GUI using Gtk.
Catagory=GUI

[Unit0]
C=Gtk.txt
Cpp=Gtk.txt
CName=main.c
CppName=main.cpp

[Project]
UnitCount=1
Type=0
IsCpp=0
Compiler=-mms-bitfields_@@_-I"<INCLUDE>\glib-2.0"_@@_-I"<INCLUDE>\atk-1.0"_@
@_-I"<INCLUDE>\gtk-2.0"_@@_-I"<INCLUDE>\pango-1.0"_@@_-I"<LIB>\glib-2.0\incl
ude"_@@_-I"<LIB>\gtk-2.0\include"
Linker=-lgtk-win32-2.0_@@_-lgdk-win32-2.0_@@_-latk-1.0_@@_-lgdk_pixbuf-2.0_@

.0_@@_-lglib-2.0_@@_-lintl_@@_-liconv
Name=GTK Project
ProjectIcon=Gtk.ico
=========================

The linker options I just copy/pasted from the `pkg-config --libs gtk+-2.0'.
Also a GTK icon (Gtk.ico) and a sample code (Gtk.txt):
=========================
#include <gtk/gtk.h>

GtkWidget *win;

int main(int argc, char *argv[])
{
        gtk_init(&argc, &argv);

        win = gtk_window_new(GTK_WINDOW_TOPLEVEL);

        g_signal_connect(G_OBJECT(win), "destroy",
G_CALLBACK(gtk_main_quit), NULL);

        gtk_widget_show(win);

        gtk_main();
}
=========================

[Dev-C++] Manual Upgrades / Downloads

[Robert Z. <rza...@ya...>]

Hey All,
     I've heard it mentioned a few times on the list that some of us
are having problems with the upgrade program for dev-cpp.  I think we
all wanted to get a newer release too, but as of right now we can't.  I
never saw a reply so I was curious, what gives, it's been 2 months and
that seems a bit long for an open source project.
     When I tried vUpdate it said the devcpp.cfg file is missing the
SBIN field.  I went ahead and searched my system for the file, but I
couldn't find anything by that name.  I played around, uninstalled and
reinstalled.  The initial configuration screen popped up a few times at
random, not at first run after install, but just randomly.  Said it
would drop the configuration file in some folder of my user's
document's and settings (sorry I didn't write down which) but I didn't
find anything.  I want to say I was the administrator or main user when
I ran that as well.  well, I guess that's about it.  
     So, If there's any work around or anything I can do, let me
know.  If I can manually build a cfg file, and try dropping it in a few
spots until it's found, maybe that'll work.  Does anyone have the
updater working on XP?  Also is there any way we can manually grab
updates to see if it's working.  Finally, thanks allot for the time you
spend in working on this.  I find Dev-cpp very useful and appreciate
your work on it allot.

Take Care,
     Robert Zaleski
