@deftypefun {int} {gnutls_init} (gnutls_session_t * @var{session}, unsigned int @var{flags})

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

@var{flags}: indicate if this session is to be used for server or client.

This function initializes the provided session. Every

session must be initialized before use, and must be deinitialized

after used by calling @code{gnutls_deinit()} .

 @code{flags} can be any combination of flags from @code{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 @code{GNUTLS_NO_EXTENSIONS} 

flag.

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