NAME
     gnutls_privkey_import_ext3 - API function

SYNOPSIS
     #include <gnutls/abstract.h>

     int  gnutls_privkey_import_ext3(gnutls_privkey_t  pkey,  void  *  userdata,
     gnutls_privkey_sign_func sign_fn,	gnutls_privkey_decrypt_func  decrypt_fn,
     gnutls_privkey_deinit_func deinit_fn, gnutls_privkey_info_func info_fn, un-
     signed int flags);

ARGUMENTS
     gnutls_privkey_t pkey
		 The private key

     void * userdata
		 private data to be provided to the callbacks

     gnutls_privkey_sign_func sign_fn
		 callback for signature operations

     gnutls_privkey_decrypt_func decrypt_fn
		 callback for decryption operations

     gnutls_privkey_deinit_func deinit_fn
		 a deinitialization function

     gnutls_privkey_info_func info_fn
		 returns  info	about  the  public  key algorithm (should not be
		 NULL)

     unsigned int flags
		 Flags for the import

DESCRIPTION
     This function will associate the given callbacks with the	gnutls_privkey_t
     type.  At	least one of the two callbacks must be non-null. If a deinitial-
     ization  function	is  provided  then   flags   is   assumed   to	 contain
     GNUTLS_PRIVKEY_IMPORT_AUTO_RELEASE.

     Note  that the signing function is supposed to "raw" sign data, i.e., with-
     out any hashing or preprocessing. In case of RSA  the  DigestInfo	will  be
     provided, and the signing function is expected to do the PKCS 1 1.5 padding
     and the exponentiation.

     The   info_fn  must provide information on the algorithms supported by this
     private key, and should support the flags	GNUTLS_PRIVKEY_INFO_PK_ALGO  and
     GNUTLS_PRIVKEY_INFO_SIGN_ALGO. It must return -1 on unknown flags.

RETURNS
     On  success,  GNUTLS_E_SUCCESS  (0) is returned, otherwise a negative error
     value.

SINCE
     3.4.0
