@deftypefun {int} {gnutls_set_default_priority} (gnutls_session_t @var{session})

@var{session}: is a @code{gnutls_session_t}  type.

Sets the default priority on the ciphers, key exchange methods,

and macs. This is the recommended method of

setting the defaults, in order to promote consistency between applications

using GnuTLS, and to allow GnuTLS using applications to update settings

in par with the library. For client applications which require

maximum compatibility consider calling @code{gnutls_session_enable_compatibility_mode()} 

after this function.

For an application to specify additional options to priority string

consider using @code{gnutls_set_default_priority_append()} .

To allow a user to override the defaults (e.g., when a user interface

or configuration file is available), the functions

@code{gnutls_priority_set_direct()}  or @code{gnutls_priority_set()}  can

be used.

@strong{Returns:} @code{GNUTLS_E_SUCCESS}  on success, or an error code.

@strong{Since:} 2.1.4
