void TestFunction() returns void. void * temp_void(); is the wrong signature for TestFunction as the return type here is void*. The correct return type would be void because that is exactly what TestFunction returns. So your example should be:
#include <acknex.h>
void TestFunction()
{
error("TestFunction was called");
}
void CallFunc(void * func)
{
void temp_void();
temp_void = func;
if(temp_void) { temp_void(); }
}
void main()
{
CallFunc(TestFunction);
}
Always learn from history, to be sure you make the same mistakes again...

well... thank you  so then it should be (in my first example)
#include <acknex.h>
int * p(); // >> without the * <<
int _function()
{
error("works now.");
}
void main()
{
p = _function;
p();
}

You did not correct the code, just wrote a comment to it, right?

nevermind  ...but seriously, especially the pointer workshop in the official tutorial needs MUCH MORE precise information about pointers. Neither in the Tutorial nor in the Manual I have read any of the information about pointers that I've learned in this thread.

The tutorial is basically a rough overview of the most basic things. It's sufficient to get your feets wet. But if you're serious about learning programming you better watch somewhere else. A good C book should do the trick.
On the one hand I think that the turial really falls off to short on this topic. On the other hand multiple indirections, pointer arithmetics and all that stuff might do no good for a beginner.

Indeed, this would only irritate and confuse new users. ...I think Something like a new page (or forum) here, where the whole community can provide their own descriptions / tutorials / workshops about all the stuff that isn't named in the official workshops wouldn't be a bad idea.

descriptions / tutorials / workshops about all the stuff that isn't named in the official workshops wouldn't be a bad idea. In theory, that would be the Wiki. But without enforced peer review or incentive, I don't see any quality content up there in the future.
