gnutls_session_supplemental_register - API function

#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);

the session for which this will be registered
the name of the supplemental data to register
the type of the supplemental data format
the function to receive the data
the function to send the data
must be zero

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.

GNUTLS_E_SUCCESS on success, otherwise a negative error code.
