NAME
gnutls_x509_crt_get_issuer_alt_name2 - API function
SYNOPSIS
#include <gnutls/x509.h>
int gnutls_x509_crt_get_issuer_alt_name2(gnutls_x509_crt_t cert, un-
signed int seq, void * ian, size_t * ian_size, unsigned int * ian_type,
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 * ian is the place where the alternative name will be copied to
size_t * ian_size
holds the size of ret.
unsigned int * ian_type
holds the type of the alternative name (one of
gnutls_x509_subject_alt_name_t).
unsigned int * critical
will be non-zero if the extension is marked as critical
(may be null)
DESCRIPTION
This function will return the alternative names, contained in the given
certificate. It is the same as gnutls_x509_crt_get_issuer_alt_name()
except for the fact that it will return the type of the alternative
name in ian_type even if the function fails for some reason (i.e. the
buffer provided is not enough).
RETURNS
the alternative issuer name type on success, one of the enumerated
gnutls_x509_subject_alt_name_t. It will return GNUTLS_E_SHORT_MEM-
ORY_BUFFER if ian_size is not large enough to hold the value. In that
case ian_size will be updated with the required size. If the certifi-
cate does not have an Alternative name with the specified sequence num-
ber then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.
SINCE
2.10.0
