Hi all. I would like to create a program that converts psmf file format (PSMF - MultimediaWiki (http://wiki.multimedia.cx/index.php?title=PSMF)) to ogv (Ogg - Wikipedia, the free encyclopedia...

I'm getting in trouble trying to do this. Firstly, a c++ problem:

This is on memory.cpp (it got compiled):
template<class T>
bool peekValue(T * value, char * offset, pid_t pid)
{
// Get...

I'm compiling c++ with extern "C" (without it doesn't work). I'm compiling exactly the same code that works on 64 bits. I'm only changing -m32 -march-i386 for compiler and -m32 for linker.

$ ldd...

Quake4 seems to be 32 bits. The other one (tileracer) too.

Okay, this seems to be the problem. By the way, I compiled openglhack32 (which is a void override of glBegin) and speedhack32 (32 bit...

I see, but I don't know any way to give you more details. I always try to give as much details as I can.

openglhack32 is compiled (and linked) with -m32 and march-i386 (or something similar). So...

I did:

$ ls /usr/lib/*hack*so
/usr/lib/openglhack32.so /usr/lib/openglhack.so /usr/lib/speedhack.so
$ export LD_PRELOAD=/usr/lib/openglhack32.so
$ quake4
ERROR: ld.so: object...

$ echo $LD_PRELOAD
speedhack.so
$ ls /usr/lib/*hack.so
/usr/lib/openglhack.so /usr/lib/speedhack.so

Well. For an unknown reason (unknown for me) LD_PRELOAD is not working for some programs, just half of them:

For instance:

quake4
ERROR: ld.so: object 'speedhack.so' from LD_PRELOAD cannot be...

Your code is not written in English nor commented:

int i;
char duom;
ifstream iv;
iv.open(file);
if (!iv.is_open())
{
cout<<"Neatidarytas '"<<file<<"' failas."<<endl;
return false;...

It is easy, if no brackets are present, it means it only executes one instruction (or block) just after that line. That means:

for a hundred of times
{
cout << "foo";
cout << "bar" <<...

The pclose() function waits for the associated process to terminate and
returns the exit status of the command as returned by wait4(2).


The wait3() and wait4() system calls are...

In unix (I guess it is like linux) all devices are files which you can open for read and write streaming, placed on /dev/ folder.

If you want to do a driver, you need to read and write the file...

Check that, it might help you.

You asked many questions but I don't know what are you trying.
Do you try to open a program and redirect both stdin and stdout?

I've got a function that does that pretty well, so if you are...

Hi everyone. I asked once here and it went well, so I'm very happy with this community.

I have a new question to ask. I would like to read&write specify memory of a process which is not the...

I think unix, linux and GNU need good advertisement.

The 99% of my partners doesn't even know what is Linux. When you talk about it they think they are too newbies to make Linux to work.

I...

Well. Now it is implemented and working well. The next part is to try to modify that function while Run-Time. Is it possible? I mean, not to launch the application with modified library, but change...

I understand your looping through STL functions. I don't need them for nothing but test purposes. That is, when I finish the library I'll erase the "LOOOL" line.

I don't need C++. Is just the...

Can anyone test it for me? Or give me a tip? I can't imagine where to continue if the library is not executed (that seems to be the problem).

Thank you for read.

EDIT: Sorry, I didn't notice...

Sorry, it is not LOOOOOL, it is LOOOLAZO at the start of the gettimeofday from speed hack. A no sense mistake, sorry.

I'm forcing that function to print twice as the time that happened but nothing happens. To test, I added print("LOOOLAZO") but it doesn't print :(. Here is the code I'm using:

speed hack library:...

I would like to do a kind of "speed hack" like Cheat Engine does...

Hi everyone. I would like to hook a system function (gettimeofday) to modify it. I guess I'll need kernel mode to do that. By the way, how could I do it (c++ or c)?

I want to modify that function...
