DESCRIPTION
       These functions are primarily useful for applications to retrieve
       supported objects from OSSL_STORE_INFO objects and for scheme specific
       loaders to create OSSL_STORE_INFO holders.

   Types
       OSSL_STORE_INFO is an opaque type that's just an intermediary holder
       for the objects that have been retrieved by OSSL_STORE_load() and
       similar functions.  Supported OpenSSL type object can be extracted
       using one of STORE_INFO_get0_TYPE().  The life time of this extracted
       object is as long as the life time of the OSSL_STORE_INFO it was
       extracted from, so care should be taken not to free the latter too
       early.  As an alternative, STORE_INFO_get1_TYPE() extracts a duplicate
       (or the same object with its reference count increased), which can be
       used after the containing OSSL_STORE_INFO has been freed.  The object
       returned by STORE_INFO_get1_TYPE() must be freed separately by the
       caller.  See "SUPPORTED OBJECTS" for more information on the types that
       are supported.

   Functions
       OSSL_STORE_INFO_get_type() takes a OSSL_STORE_INFO and returns the
       STORE type number for the object inside.  STORE_INFO_get_type_string()
       takes a STORE type number and returns a short string describing it.

       OSSL_STORE_INFO_get0_NAME(), OSSL_STORE_INFO_get0_NAME_description(),
       OSSL_STORE_INFO_get0_PARAMS(), OSSL_STORE_INFO_get0_PKEY(),
       OSSL_STORE_INFO_get0_CERT() and OSSL_STORE_INFO_get0_CRL() all take a
       OSSL_STORE_INFO and return the held object of the appropriate OpenSSL
       type provided that's what's held.

       OSSL_STORE_INFO_get1_NAME(), OSSL_STORE_INFO_get1_NAME_description(),
       OSSL_STORE_INFO_get1_PARAMS(), OSSL_STORE_INFO_get1_PKEY(),
       OSSL_STORE_INFO_get1_CERT() and OSSL_STORE_INFO_get1_CRL() all take a
       OSSL_STORE_INFO and return a duplicate of the held object of the
       appropriate OpenSSL type provided that's what's held.

       OSSL_STORE_INFO_free() frees a OSSL_STORE_INFO and its contained type.

       OSSL_STORE_INFO_new_NAME() , OSSL_STORE_INFO_new_PARAMS(),
       OSSL_STORE_INFO_new_PKEY(), OSSL_STORE_INFO_new_CERT() and
       OSSL_STORE_INFO_new_CRL() create a OSSL_STORE_INFO object to hold the
       given input object.  Additionally, for OSSL_STORE_INFO_NAME` objects,
       OSSL_STORE_INFO_set0_NAME_description() can be used to add an extra
       description.  This description is meant to be human readable and should
       be used for information printout.

SUPPORTED OBJECTS
       Currently supported object types are:

       OSSL_STORE_INFO_NAME
           A name is exactly that, a name.  It's like a name in a directory,
           but formatted as a complete URI. For example, the path in URI
           "file:/foo/bar/" could include a file named "cookie.pem", and in
           that case, the returned OSSL_STORE_INFO_NAME object would have the
           URI "file:/foo/bar/cookie.pem", which can be used by the
           application to get the objects in that file.  This can be applied
           to all schemes that can somehow support a listing of object URIs.

           For "file:" URIs that are used without the explicit scheme, the
           returned name will be the path of each object, so if "/foo/bar" was
           given and that path has the file "cookie.pem", the name
           "/foo/bar/cookie.pem" will be returned.

           The returned URI is considered canonical and must be unique and
           permanent for the storage where the object (or collection of
           objects) resides.  Each loader is responsible for ensuring that it
           only returns canonical URIs.  However, it's possible that certain
           schemes allow an object (or collection thereof) to be reached with
           alternative URIs; just because one URI is canonical doesn't mean
           that other variants can't be used.

           At the discretion of the loader that was used to get these names,
           an extra description may be attached as well.

       OSSL_STORE_INFO_PARAMS
           Key parameters.

       OSSL_STORE_INFO_PKEY
           A private/public key of some sort.

       OSSL_STORE_INFO_CERT
           An X.509 certificate.

       OSSL_STORE_INFO_CRL
           A X.509 certificate revocation list.

RETURN VALUES
       OSSL_STORE_INFO_get_type() returns the STORE type number of the given
       OSSL_STORE_INFO.  There is no error value.

       OSSL_STORE_INFO_get0_NAME(), OSSL_STORE_INFO_get0_NAME_description(),
       OSSL_STORE_INFO_get0_PARAMS(), OSSL_STORE_INFO_get0_PKEY(),
       OSSL_STORE_INFO_get0_CERT() and OSSL_STORE_INFO_get0_CRL() all return a
       pointer to the OpenSSL object on success, NULL otherwise.

       OSSL_STORE_INFO_get0_NAME(), OSSL_STORE_INFO_get0_NAME_description(),
       OSSL_STORE_INFO_get0_PARAMS(), OSSL_STORE_INFO_get0_PKEY(),
       OSSL_STORE_INFO_get0_CERT() and OSSL_STORE_INFO_get0_CRL() all return a
       pointer to a duplicate of the OpenSSL object on success, NULL
       otherwise.

       OSSL_STORE_INFO_type_string() returns a string on success, or NULL on
       failure.

       OSSL_STORE_INFO_new_NAME(), OSSL_STORE_INFO_new_PARAMS(),
       OSSL_STORE_INFO_new_PKEY(), OSSL_STORE_INFO_new_CERT() and
       OSSL_STORE_INFO_new_CRL() return a OSSL_STORE_INFO pointer on success,
       or NULL on failure.

       OSSL_STORE_INFO_set0_NAME_description() returns 1 on success, or 0 on
       failure.
