File Content Extraction 25.4
Filter SDK C Programming Guide

# ADDOCINFO

This structure contains the format, file class, and version number of the source document. The structure is defined in `adinfo.h`, and is populated by calling the function fpGetDocInfo().

    typedef struct
    {
        ENdocClass        eClass;
        ENdocFmt          eFormat;
        long              lVersion;
        unsigned long     ulAttributes;
    }
    ADDOCINFO, *ADDOCINFOPTR;

## Member Descriptions

`eClass` | The file class of the source document (for example, spreadsheet, word processor, or encapsulation format), as defined by the enumerated type `ENDocClass` in `adinfo.h`.
`eFormat` | The major format of the source document (for example Microsoft Word XML format or Corel Presentation), as defined by the enumerated type `ENdocFmt` in `adinfo.h`. The `ENdocFmt` type provides a unique ID for each major format.
`lVersion` | The version number of the file format. The number is multiplied by 1,000 (for example, 1.02 is represented by 1020).
`ulAttributes` | Other attributes of the document, as defined by the enumerated type ENdocAttributes in `adinfo.h`.

## Discussion

When format detection is enhanced in future releases, new format IDs might be added to the `ENdocFmt` enumerated type. When using this type, your code should ensure binary compatibility with future releases. For example, if you use an array to access format information based on a format ID, your code should check that the format ID is less than `Max_Fmt` before accessing the data. This ensures that new format codes are detected when you add File Content Extraction binary files from new releases to your existing installation.
