NCDF_ATTNAME

NCDF_ATTNAME

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.

Attnum

An expression containing the number of the desired attribute. The attributes for each variable are numbered from 0 to the number-of-attributes minus 1. Note that the number of attributes can be found using NCDF_VARINQ or NCDF_INQUIRE (to find the number of global variables).
