cable_netcdf_file_def_var

interface
private subroutine cable_netcdf_file_def_var(this, var_name, type, dim_names, shuffle, deflate_level)

Type	Intent	Optional		Name
class(cable_netcdf_file_t),	intent(inout)		::	this
character(len=*),	intent(in)		::	var_name	Name of the variable to define.
integer,	intent(in)		::	type	Data type of the variable, using the `CABLE_NETCDF_*` constants (e.g., `CABLE_NETCDF_INT`, `CABLE_NETCDF_REAL32`).
character(len=*),	intent(in),	optional	::	dim_names(:)	Array of dimension names for the variable. If not provided, the variable will be defined as a scalar.
logical,	intent(in),	optional	::	shuffle	Whether to apply the shuffle filter. Only used together with `deflate_level`. Defaults to false.
integer,	intent(in),	optional	::	deflate_level	Deflate compression level from 1 (fastest) to 9 (smallest). Zero or absent means no compression. Compression needs a netCDF-4 file (`CABLE_NETCDF_IOTYPE_NETCDF4C`) and is ignored for scalars.

Define a variable in the netCDF file with the specified name, dimensions, and type.
