int gnutls_x509_crq_get_dn(gnutls_x509_crq_t crq, char * buf, size_t * sizeof_buf);
ARGUMENTS
gnutls_x509_crq_t crq
should contain a gnutls_x509_crq_t structure
char * buf
a pointer to a structure to hold the name (may be null)
size_t * sizeof_buf
initially holds the size of buf
DESCRIPTION
This function will copy the name of the Certificate request
subject 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. On success 0 is returned.
