int gnutls_x509_crl_get_issuer_dn(const gnutls_x509_crl_t crl, char * buf, size_t * sizeof_buf);
ARGUMENTS
const gnutls_x509_crl_t crl
should contain a gnutls_x509_crl_t structure
char * buf
a pointer to a structure to hold the peer's name (may be null)
size_t * sizeof_buf
initially holds the size of buf
DESCRIPTION
This function will copy the name of the CRL issuer in the provided
buffer. The name will be in the form "C=xxxx,O=yyyy,CN=zzzz" as
described in RFC2253. The output string will be ASCII or UTF-8
encoded, depending on the certificate data.
If buf 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_buf will be updated
with the required size, and 0 on success.
