static object* find_throw_ob	(	object *	op,
		const char *	request
	)		[static]

Find an object to throw.

If we request an object, then we search for it in the inventory of the owner (you've got to be carrying something in order to throw it!). If we didnt request an object, then the top object in inventory (that is "throwable", ie no throwing your skills away!) is the object of choice. Also check to see if object is 'throwable' (ie not applied cursed obj, worn, etc).

Parameters:

op	object wishing to throw.
request	requested item to throw.

Returns:

throwable object, NULL if none suitable found.

This always returns 0 - return value is used by calling function such that if it returns true, player gets exp in that skill. This the effect here can be done on demand, we probably don't want to give infinite exp by returning true in any cases.

Singing skill handling.

This skill allows the player to pacify nearby creatures. There are few limitations on who/what kind of non-player creatures that may be pacified. Right now, a player may pacify creatures which have Int == 0. In this routine, once successfully pacified the creature gets Int=1. Thus, a player may only pacify a creature once. BTW, I appologize for the naming of the skill, I couldnt think of anything better! -b.t.
