gnutls_init(3)                    gnutls                   gnutls_init(3)

NAME         top

       gnutls_init - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       int gnutls_init(gnutls_session_t * session, unsigned int flags);

ARGUMENTS         top

       gnutls_session_t * session
                   is a pointer to a gnutls_session_t type.

       unsigned int flags
                   indicate if this session is to be used for server or
                   client.

DESCRIPTION         top

       This function initializes the provided session. Every session must
       be initialized before use, and after successful initialization and
       use must be deinitialized by calling gnutls_deinit().

        flags can be any combination of flags from gnutls_init_flags_t.

       Note that since version 3.1.2 this function enables some common
       TLS extensions such as session tickets and OCSP certificate status
       request in client side by default. To prevent that use the
       GNUTLS_NO_DEFAULT_EXTENSIONS flag.

       Note that it is never mandatory to use gnutls_deinit() after this
       function fails.  Since gnutls 3.8.0, it is safe to unconditionally
       use gnutls_deinit() even after failure regardless of whether the
       memory was initialized prior to gnutls_init(); however, clients
       wanting to be portable to older versions of the library should
       either skip deinitialization on failure, or pre-initialize the
       memory passed in to gnutls_init() to all zeroes via memset() or
       similar.

RETURNS         top

       GNUTLS_E_SUCCESS on success, or an error code.
