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);


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


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.


GNUTLS_E_SUCCESS on success, otherwise a negative error code.
