int gnutls_x509_crt_get_authority_key_gn_serial(gnutls_x509_crt_t cert, unsigned int seq, void * alt, size_t * alt_size, unsigned int * alt_type, void * serial, size_t * serial_size, unsigned int * critical);
- gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t type
- unsigned int seq
specifies the sequence number of the alt name (0 for the first one, 1 for the second etc.)
- void * alt
is the place where the alternative name will be copied to
- size_t * alt_size
holds the size of alt.
- unsigned int * alt_type
holds the type of the alternative name (one of gnutls_x509_subject_alt_name_t).
- void * serial
buffer to store the serial number (may be null)
- size_t * serial_size
Holds the size of the serial field (may be null)
- unsigned int * critical
will be non-zero if the extension is marked as critical (may be null)
This function will return the X.509 authority key identifier when stored as a general name (authorityCertIssuer) and serial number.
Because more than one general names might be stored
seq can be used as a counter to request them all until GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.
On success, GNUTLS_E_SUCCESS (0) is returned, GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the extension is not present, otherwise a negative error value.
