How do I write a callback function that calls to a function inside the executable? (linux)

Hi,
WARNING: ultimate noob!
Let's say if I have this function

//Executable
//Called function
void CallMeSunny( void )
{
//code
}

I want to callback to it from a shared library. How do I do that? (I just need something simple that works)
I tried to implement some of the snippets online. But, all were to simplified that I couldn't understand them.

Platform: Linux
Language: C

Creating a shared library may be an advanced topic for a "noob". You may want to begin with simply including external files, or object code. Either way, here is a good link:

Note: You can include code files as external resources instead of using a library. #include "whatever.c"

Unfortunately, this doesn't apply to what I need : (((

I will try to explain what I am trying to do better:

//Executable

void functionA()
{
//code that calls to functions inside EXE
}

void functionB()
{
//code that calls to functions inside EXE
}

void functionC()
{
//code that calls to functions inside EXE
}

//Shared Library
void functionSL()
{
// I need to call functionA(), functionB() & functionC()
}

So, instead of writing three callback functions.
I did the following:

//Executable
void functionABC()
{
functionA();
functionB();
functionC();
}

//Shared library
//Must call functionABC()

Therefore, unfortunately, even if I would create a shared library, and place functionA(), functionB() functionC() inside it, I will still have create Callback functions for the functions that are called from within functionA/B/C() ><

Furthermore, this is not my code. I am trying to add some simple functionality there. I did it on windows, and now I need to test it on Linux. But, I can't seem to get the right syntax for callback functions there.

Any ideas on "Callback functions to a function that is inside an executable?"
Thanx!

You would need to pass a pointer to the function into the library function that is to make the call back. The chances are that you can rethink your design and make things a lot simpler for yourself by just using variables between your executable and library function.

I appreciate the suggestions. But, for MANY circumstances, I NEED to write it that way. I added some more detail to my post, could you kindly view it?

Yes, I understood what you are trying to do, which is why I made the comments that I did. However, in order to achieve this you need to pass a function pointer into the function of the shared library, just the same as in Windows.
Define your shared library function something like:

C++

void func(void (*callback)())
{
}

changing the return type and other parameters as necessary. Then you can call your function with a pointer to your callback routine as follows:

C++

func(functionA);

which is best linux os for making media server in web browser

What type of media server? Like a streaming media server? Normally, I prefer Fedora, but Ubuntu is the prefered flavor for Airtime (a streaming media server). Ubuntu would probably be the best as its the most popular.

SLITAZ is small and tiny (30mb only I used it and added some of my own software stack (node.js) to write a tiny server. :P
Linux From Scratch works if you don't like any OS. Personally if you are doing a media server I would actually start from either slitaz or LFS and build my way up. But thats just me.

Is there a way to make a ssh connection without specifying an username

as subject says, i'd like to make ssh connection without specifying an username and let server give me an prompt text like "username:" or "login as:" so that I can type my account by myself.
The default way ssh gave is using the username in env as the account i want to connect in remote server, or I can specify a user in the form "username@host".
I ask this for special use, thanks in advance!

Best Wishes!

I don't think the SSH protocol allows doing what you want. The connection must be authenticated before the server can output anything to the client terminal.

Thanks man, but is there any official document talked about this or any statement that exactly identified that so that I can make sure? Any link would be suffice, thanks again.

Hi I am trying to learn so I started looking for free course's on Programming.

I found one I think might get Me started. But since My work will not be graded by the mit staff I hope to get one of the other members to look at my work and grade it. So that I can use that grade to determine how much more review I need on each part of the process.

I want to learn and am in need of some help. If You are not willing to I will understand.

Thank You in advance

Here is the thing:

You must have to remember that PHP run on server side it has nothing to do in Client side. So, the fact is you cannot run outlook using PHP...

But the thing you are looking for is related with the browser html and browser.
here is an example:

HTML

<a href="mailto:someone@somewhere.com">Mail me</a>

When a user click on the the link browser open the default eamil client installed in your computer. follow the link[^] you will get clear view
