The NCDF_ATTNAME function returns the name of an attribute in a NetCDF file given its ID.

Syntax


Result = NCDF_ATTNAME( Cdfid [, Varid] , Attnum [, /GLOBAL])

Return Value


Returns the specified attribute’s name or an empty string (“”) if there is no such attribute.

Arguments


Cdfid

The NetCDF ID, returned from a previous call to NCDF_OPEN, NCDF_CREATE, or NCDF_GROUPDEF.

Varid

The NetCDF variable ID, returned from a previous call to NCDF_VARDEF or NCDF_VARID, or the name of the variable. If the GLOBAL keyword is set, this argument must be omitted.
