int gnutls_x509_crl_get_dn_oid(gnutls_x509_crl_t crl, int indx, void * oid, size_t * sizeof_oid);
ARGUMENTS
gnutls_x509_crl_t crl
should contain a gnutls_x509_crl_t structure
int indx
Specifies which DN OID to send. Use zero to get the first one.
void * oid
a pointer to a structure to hold the name (may be null)
size_t * sizeof_oid
initially holds the size of 'oid'
DESCRIPTION
This function will extract the requested OID of the name of the CRL
issuer, specified by the given index.
If oid is null then only the size will be filled.
RETURNS
GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is
not long enough, and in that case the sizeof_oid will be updated
with the required size. On success 0 is returned.
