Var.ReadBytes doesn't work? Maybe we need to wrap nc_get_vara_string? PRs are welcome.
How should I use Var.ReadBytes: it returns an error and takes a byte slice/array?
// ReadBytes reads the entire variable v into data, which must have enough
// space for all the values (i.e. len(data) must be at least v.Len()).
func (v Var) ReadBytes(data []byte) error {
if err := okData(v, CHAR, len(data)); err != nil {
return err
}
return newError(C.nc_get_var_text(C.int(v.ds), C.int(v.id), (*C.char)(unsafe.Pointer(&data[0]))))
}
I think you need to create a ReadStrings
methods that uses C.nc_get_var_string
.
func (v Var) ReadStrings(data []string) error
I think It would be good for Attr as well :
func (a Attr) ReadStrings(data []string) error
Hi,
Hw to read string variable data?
This is my cdl file:
`netcdf test { dimensions: station = 9 ; ... variables: string station_name(station) ; ... // global attributes: ... data:
station_name = "W1", "W2", "W3", "W4", "W5", "W6", "W7", "W8", "W9" ;
...`
How can I read the string data?
Thanks.
