Description
|
ANfileinfo retrieves the total number of the four kinds of annotations and stores them in the appropriate parameters. The total number of data labels of all data objects in the file is stored in n_data_labels. The total number of data descriptions of all data objects in the file is stored in n_data_descs. The total number of file labels is stored in n_file_labels and the total number of file descriptions in n_file_descs. |
|
|
|
Note that the numbers of data labels and descriptions refer to the total number of data labels and data descriptions in the file, not for a specific object. Use ANnumann to determine these numbers for a specific object. |

This routine is generally used to find the range of acceptable indices for ANselect calls. |
