@deftypefun {int} {gnutls_pkcs11_obj_import_url} (gnutls_pkcs11_obj_t @var{obj}, const char * @var{url}, unsigned int @var{flags})

@var{obj}: The structure to store the object

@var{url}: a PKCS 11 url identifying the key

@var{flags}: Or sequence of GNUTLS_PKCS11_OBJ_* flags

This function will "import" a PKCS 11 URL identifying an object (e.g. certificate)

to the @code{gnutls_pkcs11_obj_t}  type. This does not involve any

parsing (such as X.509 or OpenPGP) since the @code{gnutls_pkcs11_obj_t}  is

format agnostic. Only data are transferred.

If the flag @code{GNUTLS_PKCS11_OBJ_FLAG_OVERWRITE_TRUSTMOD_EXT}  is specified

any certificate read, will have its extensions overwritten by any

stapled extensions in the trust module.

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a

negative error value.

@var{n_list}: Initially should hold the maximum size of the list. Will contain the actual size.

@var{url}: A PKCS 11 url identifying a set of objects

@var{flags}: Or sequence of GNUTLS_PKCS11_OBJ_* flags

This function will initialize and set values to an object list

by using all objects identified by a PKCS 11 URL.

This function will enumerate all the objects specified by the PKCS@code{11}  URL

provided. It expects an already allocated  @code{p_list} which has * @code{n_list} elements,

and that value will be updated to the actual number of present objects. The

 @code{p_list} objects will be initialized and set by this function.

To obtain a list of all available objects use a  @code{url} of 'pkcs11:'.

All returned objects must be deinitialized using @code{gnutls_pkcs11_obj_deinit()} .

The supported in this function  @code{flags} are @code{GNUTLS_PKCS11_OBJ_FLAG_LOGIN} ,
