Calling a function before it exists

Hi,

I'm making a Static Library that calls a function that does not yet
exists, but is defined by the program that uses the library.
How can i accomplish this? I know it's possible with DLL's, but
that's not what i want.

Thx in advanced.

I didn't really understand you but this may help: (I hope)


Wrong

Code:

---

int main()
{
  myfunction(5,3);
  return 0;
}

int myfunction(int param1, int param2)
{
  lalalala;
  return 0;
}

---

Right (Except for the lalala thingey :P)

Code:

---

int myfunction(int, int)

int main()
{
  myfunction(5,3);
  return 0;
}

int myfunction(int param1, int param2)
{
  lalalala;
  return 0;
}

Tell me if this is what you meant.

No, fun though to be treated like a beginner:p .
What you posted is for the compiler to know that this function
exists before it stumbled across it's definition. What i ment
was that it called a function from another yet to be coded
source code.

the library:

Code:

---


void blab();

void blob()
{
blab();
}

---

the source that is created after the library has been compiled

Code:

---


void blab()
{
}

you pass the function to be called as a parameter to some call into the library.

Could you go more into this?

Or, why not just use polymorphism. We're not limitted to C anymore, remember?

Define a base class with a virtual member function and make children in another project.

You're able to have a pointer to a function?
Aren't you able to tell the lib wich function to run?
Then it's all solved isn't it?

Try this one
I just love a google search
