gnutls_rehandshake(3)						      gnutls						     gnutls_rehandshake(3)

NAME
gnutls_rehandshake - API function SYNOPSIS
#include <gnutls/gnutls.h> int gnutls_rehandshake(gnutls_session_t session); ARGUMENTS
gnutls_session_t session is a gnutls_session_t structure. DESCRIPTION
This function will renegotiate security parameters with the client. This should only be called in case of a server. This message informs the peer that we want to renegotiate parameters (perform a handshake). If this function succeeds (returns 0), you must call the gnutls_handshake() function in order to negotiate the new parameters. Since TLS is full duplex some application data might have been sent during peer's processing of this message. In that case one should call gnutls_record_recv() until GNUTLS_E_REHANDSHAKE is returned to clear any pending data. Care must be taken if rehandshake is mandatory to terminate if it does not start after some threshold. If the client does not wish to renegotiate parameters he will should with an alert message, thus the return code will be GNUTLS_E_WARN- ING_ALERT_RECEIVED and the alert will be GNUTLS_A_NO_RENEGOTIATION. A client may also choose to ignore this message. RETURNS
GNUTLS_E_SUCCESS on success, otherwise a negative error code. REPORTING BUGS

gnutls_credentials_set(3)					      gnutls						 gnutls_credentials_set(3)

NAME
gnutls_credentials_set - API function SYNOPSIS
#include <gnutls/gnutls.h> int gnutls_credentials_set(gnutls_session_t session, gnutls_credentials_type_t type, void * cred); ARGUMENTS
gnutls_session_t session is a gnutls_session_t structure. gnutls_credentials_type_t type is the type of the credentials void * cred is a pointer to a structure. DESCRIPTION
Sets the needed credentials for the specified type. Eg username, password - or public and private keys etc. The cred parameter is a structure that depends on the specified type and on the current session (client or server). In order to minimize memory usage, and share credentials between several threads gnutls keeps a pointer to cred, and not the whole cred structure. Thus you will have to keep the structure allocated until you call gnutls_deinit(). For GNUTLS_CRD_ANON, cred should be gnutls_anon_client_credentials_t in case of a client. In case of a server it should be gnutls_anon_server_credentials_t. For GNUTLS_CRD_SRP, cred should be gnutls_srp_client_credentials_t in case of a client, and gnutls_srp_server_credentials_t, in case of a server. For GNUTLS_CRD_CERTIFICATE, cred should be gnutls_certificate_credentials_t. RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code is returned. REPORTING BUGS
