I'm thinking of defining structs for all similar types of IIO output
formats in iio.h like this:
struct iio_val_int_plus_micro {
int val_int;
int val_micro;
};
struct iio_val_int_plus_nano {
int val_int;
int val_nano;
};
struct iio_val_int_plus_micro_db {
int val_int;
int val_micro_db;
};
struct iio_val_fractional {
int dividend;
int divisor;
};
struct iio_val_fractional_log2 {
int dividend;
int divisor;
};
Do you agree?
Regards,
Gerald
