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.
