Find the nearest symbol equal to or less than the supplied address (e.g., the label for the enclosing function).

Parameters

addr	The address to look up.
symbol	Return reference for symbol string.
symaddr	Return reference for symbol address.
nextaddr	Address of following symbol (for determining valid range of symbol).

Return values

True	if a symbol was found.
