template<class MAP>

size_t @587::add_prefix	(	MAP &	_map,
		const std::string &	prefix
	)			[inline, static]

add a prefix (if needed) to all keys of the map the previus key is removed

Parameters:

	_map	map to be modified
	prefix	prefix to be added

Returns:

number of modified keys

loop over all entries to find the proper keys
