gnutls_init(3) gnutls gnutls_init(3)
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 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 ex-
tensions such as session tickets and OCSP certificate status request in
client side by default. To prevent that use the GNUTLS_NO_DEFAULT_EXTEN-
SIONS flag.
Note that it is never mandatory to use gnutls_deinit() after this func-
tion 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 deinitial-
ization on failure, or pre-initialize the memory passed in to
gnutls_init() to all zeroes via memset() or similar.
RETURNS
GNUTLS_E_SUCCESS on success, or an error code.
