Calling Sequence

ncdf_datatype = NCDF_CastDataType(variable)

Arguments

variable: The IDL variable for which you want a netCDF data type.
Or, if the TYPE keyword is set, the variable type index you wish
to convert. Or, if the TNAME keyword is set, the variable type
name you wish to convert.

Keywords

TYPE: If set, the positional argument is an IDL variable type of
the sort returned by the SIZE function with the TYPE keyword set.

type = Size(variable, /TYPE)
TNAME: If set, the positional argument is an IDL variable type of
the sort returned by the SIZE function with the TNAME keyword set.

type = Size(variable, /TNAME)

Return Value

ncdf_datatype: The netCDF data type of the variable. Possible values are
'BYTE', 'CHAR', 'SHORT', 'LONG', 'FLOAT' and 'DOUBLE'.

Notes

The program is designed to work with the NCDF_FILE object and related programs.
