Functions
int	iioutils_break_up_name (const char *full_name, char **generic_name)
: the channel name
iioutils_get_type() - find and process _type attribute data : output whether channel is signed : output how many bytes the channel storage occupies : output a bit mask for the raw data : big endian : the iio device directory : the channel type name

int	build_channel_array (const char *device_dir, struct iio_channel_info **ci_array, int *counter)
: top level type instance name
find_type_by_name() - function to match top level types by name : the type of top level instance being sort Typical types this is used for are device and trigger.
