What Can This Function Possibly Do?

I'm all lost...

libEntity *__cdecl cyLibDataEntry254(libEntity *E, entityPair *P)
{
  libEntity *L; // edx@1
  libEntity *Result; // eax@5
  libEntity *R; // edx@7

  L = E->L;
  if ( L )
  {
    L->R = E->R;
again:
    R = E->R;
    if ( R )
    {
      Result = E->L;
      R->L = Result;
    }
    else
    {
      if ( P->R != E )
        debugfail(254, "cglib/src/cylibdataentry.cpp");
      Result = E->L;
      P->R = Result;
    }
    E->L = 0;
    E->R = 0;
    return Result;
  }
  if ( P->L == E )

    P->L = E->R;
    goto again;
  }

    debugfail(243, "cglib/src/cylibdataentry.cpp");
  return Result;
}

No "Infinite Set"? I know you were lying.

I would be happy if you could show me an empty set.

It's a part of a bigger algorithm. E and P might be heavily aliased (refer to same or very close nodes).

Also it might be buggy, notice how it might return undefined value (Result) if all checks fail.

struct Might look something like this..?
..wait, how you do recursive structs.... =/


probably some typedef here?

struct libEntity{
       libEntity *E, *R, *L; //could be left & right, e is up/down?(maybe?)
       };

struct entityPair{
       libEntry  *E, *R;};

struct Might look something like this..? plus/minus a lot probably,,

struct libEntity{
       libEntity *E, *R, *L; //could be left & right (circular perhaps?), e is up/down?(maybe?)
       };

struct entityPair{
       libEntry  *E, *R;}; //two linked objects? or two pieces of an object? E & R..?

You know, I'm tempted to say it's part of the code of a self-balancing tree, maybe a red-black tree or a splay tree.
I'm a bit too drunk to be arsed to figure out exactly which step this does right now.

You are too stupid to notice that

  L = E->L;
  if ( L )
  {
    L->R = E->R;
does list unlinking. But if I name the vars...

  P = E->Prev;
  if ( P )
  {
    P->Next = E->Next;
...now even niggers will understand the code.
