This function 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 its HDF reference number.
Result = HDF_AN_NUMANN(Annotation_id, Annotation_type, Object_tag, Object_ref)
Returns the number of annotations or FAIL (-1) otherwise.
HDF AN interface identifier returned by HDF_AN_START.
Type of the annotation. The following table lists the valid values of the parameter Annotation_type in the left column, and the corresponding values of the parameter Annotation_tag in the right column.

0 = Data Label (AN_DATA_LABEL) |
104 (DFTAG_DIL) |

1 = Data Description (AN_DATA_DESC) |
105 (DFTAG_DIA) |

2 = File Label (AN_FILE_LABEL) |
100 (DFTAG_FID) |

3 = File Description (AN_FILE_DESC) |
101 (DFTAG_FD) |
HDF tag of the object.
HDF reference number of the object. Since this routine is implemented only to obtain the total number of data annotations and not file annotations, the valid values of Annotation_type are:
To obtain the total number of file annotations or all data annotations, use HDF_AN_FILEINFO.
