gnutls_x509_crq_get_attribute_info - Get attribute id
int gnutls_x509_crq_get_attribute_info(gnutls_x509_crq_t cert, int
indx, void * oid, size_t * sizeof_oid);
should contain a gnutls_x509_crq_t structure
int indx Specifies which attribute OID to send. Use zero to get the
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
On success, GNUTLS_E_SUCCESS is returned, otherwise a negative value in
case of an error. If your have reached the last extension available
GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
