NAME

gnutls_session_supplemental_register - API function

SYNOPSIS

#include <gnutls/gnutls.h>

int gnutls_session_supplemental_register(gnutls_session_t session, const char * name, gnutls_supplemental_data_format_type_t type, gnutls_supp_recv_func recv_func, gnutls_supp_send_func send_func, unsigned flags);

ARGUMENTS

gnutls_session_t session: the session for which this will be registered
const char * name: the name of the supplemental data to register
gnutls_supplemental_data_format_type_t type: the type of the supplemental data format
gnutls_supp_recv_func recv_func: the function to receive the data
gnutls_supp_send_func send_func: the function to send the data
unsigned flags: must be zero

DESCRIPTION

This function will register a new supplemental data type (rfc4680). The registered supplemental functions will be used for that specific session. The provided type must be an unassigned type in gnutls_supplemental_data_format_type_t.

If the type is already registered or handled by GnuTLS internally GNUTLS_E_ALREADY_REGISTERED will be returned.

As supplemental data are not defined under TLS 1.3, this function will disable TLS 1.3 support for the given session.

RETURNS

GNUTLS_E_SUCCESS on success, otherwise a negative error code.

SINCE

3.5.5
