gnutls_x509_crt_get_extension_oid - get the specified extension OID
int gnutls_x509_crt_get_extension_oid(gnutls_x509_crt_t cert, int indx,
void * oid, size_t * sizeof_oid);
should contain a gnutls_x509_crt_t structure
int indx Specifies which extension OID to send. Use zero to get the
void * oid a pointer to a structure to hold the OID (may be null)
size_t * sizeof_oid
initially holds the size of oid
This function will return the requested extension OID in the
certificate. The extension OID will be stored as a string in the
On success, GNUTLS_E_SUCCESS (zero) is returned, otherwise an error
