Аргументы (Arguments)
gnutls_x509_crq_t crq
should contain a gnutls_x509_crq_t type
const char * oid

void * buf a pointer to a structure to hold the name (may be

Описание (Description)
This function will extract the part of the name of the
Certificate request subject, specified by the given OID. The
output will be encoded as described in RFC2253. The output string
will be ASCII or UTF-8 encoded, depending on the certificate
data.
Some helper macros with popular OIDs can be found in
gnutls/x509.h If raw flag is (0), this function will only return
known OIDs as text. Other OIDs will be DER encoded, as described
in RFC2253 -- in hex format with a 'using
gnutls_x509_dn_oid_known()
.
Возвращаемое значение (Return value)
GNUTLS_E_SHORT_MEMORY_BUFFER
if the provided buffer is not long
enough, and in that case the * buf_size will be updated with the
required size. On success 0 is returned.
