gnutls_server_name_get(3) gnutls gnutls_server_name_get(3)
gnutls_server_name_get - API function
#include <gnutls/gnutls.h>
int gnutls_server_name_get(gnutls_session_t session, void * data,
size_t * data_length, unsigned int * type, unsigned int indx);
gnutls_session_t session
is a gnutls_session_t type.
void * data will hold the data
size_t * data_length
will hold the data length. Must hold the maximum size
of data.
unsigned int * type
will hold the server name indicator type
unsigned int indx
is the index of the server_name
This function will allow you to get the name indication (if any),
a client has sent. The name indication may be any of the
enumeration gnutls_server_name_type_t.
If type is GNUTLS_NAME_DNS, then this function is to be used by
servers that support virtual hosting, and the data will be a null
terminated IDNA ACE string (prior to GnuTLS 3.4.0 it was a UTF-8
string).
If data has not enough size to hold the server name
GNUTLS_E_SHORT_MEMORY_BUFFER is returned, and data_length will
hold the required size.
indx is used to retrieve more than one server names (if sent by
the client). The first server name has an index of 0, the second
1 and so on. If no name with the given index exists
GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.
On success, GNUTLS_E_SUCCESS (0) is returned, on UTF-8 decoding
error GNUTLS_E_IDNA_ERROR is returned, otherwise a negative error
code is returned.
