NAME

       gnutls_init - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

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

ARGUMENTS

       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

       This  function  initializes the current session to null. Every session must be initialized
       before use, so internal structures can be allocated.  This function  allocates  structures
       which  can  only  be  free'd  by calling gnutls_deinit().  Returns GNUTLS_E_SUCCESS (0) on
       success.

        flags can be one of GNUTLS_CLIENT,  GNUTLS_SERVER,  GNUTLS_DATAGRAM,  GNUTLS_NONBLOCK  or
       GNUTLS_NOSIGNAL (since 3.4.2).

       The flag GNUTLS_NO_REPLAY_PROTECTION will disable any replay protection in DTLS mode. That
       must only used when replay protection is achieved using other means.

       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_EXTENSIONS flag.

RETURNS

       GNUTLS_E_SUCCESS on success, or an error code.
