DLIST_CONTAINS

[Tom Jansen]

Hello,

I need to check if an entry is part of a dlinkedlist or not. My searches in
samba code did not give me such a functions.

I'm not a real C-Macro god at all, so I challenge _you_  to write a nice Macro
for the following function :-)

This Macro should become part of include/dlinklist.h

/* check if an element is part of the list. */
int DLIST_CONTAINS(list, p) {
	if (!p || !list) return False;
	do {
		if (p == list) return True;
		p = p->next;
	} while (p);
	return False;
}

Thank you in advance,

    Tom

PS Yes Andrew, this is for removing the filedescriptors from libsmbclient.so
