should contain a gnutls_x509_crq_t type
Specifies which attribute number to get. Use (0) to
get the first one.
void * oid a pointer to a structure to hold the OID
size_t * sizeof_oid
initially holds the maximum size of oid , on return
holds actual size of oid .
This function will return the requested attribute OID in the
certificate, and the critical flag for it. The attribute OID
will be stored as a string in the provided buffer. Use
gnutls_x509_crq_get_attribute_data() to extract the data.
If the buffer provided is not long enough to hold the output,
then * sizeof_oid is updated and GNUTLS_E_SHORT_MEMORY_BUFFER
will be returned.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
negative error code in case of an error. If your have reached
the last extension available
GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
