gnutls_x509_crq_get_subject_alt_name - API function
int gnutls_x509_crq_get_subject_alt_name(gnutls_x509_crq_t crq,
unsigned int seq, void * ret, size_t * ret_size, unsigned int *
ret_type, unsigned int * critical);
should contain a gnutls_x509_crq_t type
unsigned int seq
specifies the sequence number of the alt name, 0 for the
first one, 1 for the second etc.
void * ret is the place where the alternative name will be copied to
size_t * ret_size
holds the size of ret.
unsigned int * ret_type
holds the gnutls_x509_subject_alt_name_t name type
unsigned int * critical
will be non-zero if the extension is marked as critical
(may be null)
This function will return the alternative names, contained in the given
certificate. It is the same as gnutls_x509_crq_get_subject_alt_name()
except for the fact that it will return the type of the alternative
name in ret_type even if the function fails for some reason (i.e. the
buffer provided is not enough).
the alternative subject name type on success, one of the enumerated
gnutls_x509_subject_alt_name_t. It will return
GNUTLS_E_SHORT_MEMORY_BUFFER if ret_size is not large enough to hold
the value. In that case ret_size will be updated with the required
size. If the certificate request does not have an Alternative name
with the specified sequence number then
GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.
