int gnutls_x509_crq_get_subject_alt_name(gnutls_x509_crq_t cert, unsigned int seq, void * ret, size_t * ret_size, unsigned int * ret_type, unsigned int * critical);
ARGUMENTS
gnutls_x509_crq_t cert
should contain a gnutls_x509_crq_t structure
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)
DESCRIPTION
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).
RETURNS
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.
