NAME

       gnutls_x509_crt_get_authority_key_gn_serial - API function

SYNOPSIS

       #include <gnutls/x509.h>

       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);

ARGUMENTS

       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)

DESCRIPTION

       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.

RETURNS

       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.

SINCE

       3.0
