gnutls_x509_dn_oid_known - API function
int gnutls_x509_dn_oid_known(const char * oid);
- const char * oid
holds an Object Identifier in a null terminated string
This function will inform about known DN OIDs. This is useful since
functions like gnutls_x509_crt_set_dn_by_oid()
use the information
on known OIDs to properly encode their input. Object Identifiers
that are not known are not encoded by these functions, and their
input is stored directly into the ASN.1 structure. In that case of
unknown OIDs, you have the responsibility of DER encoding your
1 on known OIDs and 0 otherwise.
