HDF_AN_ANNLEN Returns the number of characters contained in the HDF AN annotation specified by the annotation identifier Annotation_id.
HDF_AN_ANNLIST Obtains a list of identifiers of the annotations specified by the parameter Annotation_type and attached to the object identified by Object_tag, and Object_ref.
HDF_AN_ATYPE2TAG Returns the HDF tag that corresponds to the annotation type specified by the parameter Annotation_type.
HDF_AN_CREATE Creates an HDF AN data annotation of type Annotation_type specified by Object_tag and Object_ref.
HDF_AN_CREATEF Creates an HDF AN file annotation of the type specified by the parameter Annotation_type.
HDF_AN_END Terminates access to the HDF AN interface identified by Annotation_id, which is previously initialized by a call to HDF_AN_START.
HDF_AN_ENDACCESS Terminates access to the annotation identified by the parameter Annotation_id.
HDF_AN_FILEINFO Retrieves the total number of the four kinds of annotations and stores them in the appropriate parameters
HDF_AN_GET_TAGREF Retrieves the HDF tag and reference number of the annotation identified by its index and by its annotation type.
HDF_AN_ID2TAGREF Retrieves the HDF tag/reference number pair of the HDF AN annotation identified by its annotation identifier.
HDF_AN_NUMANN Returns the total number of HDF AN annotations that are of a given type and that are attached to the object identified by its HDF tag and HDF reference number.
HDF_AN_READANN Reads the HDF AN annotation identified by the annotation identifier and stores the annotation into a variable.
HDF_AN_SELECT Obtains the HDF AN identifier of the annotation specified by its index and by its annotation type.
HDF_AN_START Initializes the HDF AN interface for the specified file.
HDF_AN_TAG2ATYPE Returns the HDF AN annotation type that corresponds to the specified HDF annotation tag.
HDF_AN_TAGREF2ID Returns the HDF AN identifier of the annotation specified by its HDF tag and its HDF reference number.
HDF_AN_WRITEANN Writes the annotation text provided in the parameter annotation to the HDF AN annotation specified by the parameter Annotation_id.
HDF_BROWSER Opens a GUI to view contents of HDF, HDF-EOS, or NetCDF file.
HDF_CLOSE Closes the HDF file associated with the given file handle.
