gnutls_set_default_priority_append - Man Page

API function


#include <gnutls/gnutls.h>

int gnutls_set_default_priority_append(gnutls_session_t session, const char * add_prio, const char ** err_pos, unsigned flags);


gnutls_session_t session

is a gnutls_session_t type.

const char * add_prio

is a string describing priorities to be appended to default

const char ** err_pos

In case of an error this will have the position in the string the error occurred

unsigned flags

must be zero


Sets the default priority on the ciphers, key exchange methods, and macs with the additional options in  add_prio . This is the recommended method of setting the defaults when only few additional options are to be added. This promotes consistency between applications using GnuTLS, and allows GnuTLS using applications to update settings in par with the library.

The  add_prio string should start as a normal priority string, e.g., with ':'.

To allow a user to override the defaults (e.g., when a user interface or configuration file is available), the functions gnutls_priority_set_direct() or gnutls_priority_set() can be used.


GNUTLS_E_SUCCESS on success, or an error code.
