I hope I don't inconvenience you...

Code:

#include <acknex.h>

void foo_startup_bar()
{
	printf("surprise");
}

Thanks, we'll reword the text.

What is to be said against fixing the bug in this case?

Changing software behavior just to match the documentation could break existing code - therefore we do that only when there's a real reason for it, such as improving or fixing something. In all other cases we change the documentation.

my personal quote of the week^^.

However, if "startup" is registered from everywhere within the identifier, this limits the programmer, as he can not use this word.

AND

in all other places, theses marks occur ONLY at the end of the identifier. For example in shadercode where we use_var, _bmap etc. This behaviour for "startup" doesnt match the general behaviour, is not intended, so it's a bug.

But that code was already broken in the first place.

There is: As Rakscha pointed out the currently implemented behaviour is totally inconsistent with the rest of the software.

Additionally the "_startup" check does not take into account the number of arguments of the function (does not make any sense to me. If it's a startup it shouldn't have any parameters!) This makes the whole thing even more dangerous.

Code:

#include <acknex.h>

void show_startup_text(TEXT* t)
{
	if (t)
		t->flags |= SHOW;
}

This small piece of code will cause your application to crash. Even worse on my machine the crash occurs randomly.
