Here is the caller graph for this function:

size_t CharacterPool::getPoolPos	(	SUBPOOLS	p,
		size_t *	start
	)			const

Return the position and length of the pool.

Returns 0 and sets start=0 if the pool p is not allocated.

Remember that start+length is not the last character of the pool in question, but the first character of the adjacent pool (if any!!).

Parameters:

	p	the pool in question.
	start	pointer to size_t where the start position will be stored.

Returns:: the length of the pool. If zero, an error occured.

Parameters:

pos the position of the character to retrieve. Zero based, must be less than the value reported by getPoolLength()

Returns:: The character at the specified position, or zero upon error, i.e. pos greater than or equal to getPoolLength()
