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 structure

       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
