    };

### struct EBookBackendSExpClass

    struct EBookBackendSExpClass {
    };

### e_book_backend_sexp_new ()

    EBookBackendSExp *  e_book_backend_sexp_new             (const gchar *text);

Creates a new EBookBackendSExp from `text`.

`text` : | an s-expression to parse
Returns : | a new EBookBackendSExp

### e_book_backend_sexp_text ()

    const gchar *       e_book_backend_sexp_text            (EBookBackendSExp *sexp);

`sexp` : | an EBookBackendSExp
Returns : | the text expression

Since 3.8

### e_book_backend_sexp_match_vcard ()

    gboolean            e_book_backend_sexp_match_vcard     (EBookBackendSExp *sexp,

Checks if `vcard` matches `sexp`.

`sexp` : | an EBookBackendSExp
`vcard` : | a vCard string
Returns : | `TRUE` if the vCard matches, `FALSE` otherwise

### e_book_backend_sexp_match_contact ()

    gboolean            e_book_backend_sexp_match_contact   (EBookBackendSExp *sexp,
                                                             EContact *contact);
