#include <gnutls/x509.h>
int
gnutls_x509_crt_get_extension_by_oid( |
gnutls_x509_crt_t cert, |

unsigned int * critical); |
should contain a gnutls_x509_crt_t structure
holds an Object Identified in null terminated string
In case multiple same OIDs exist in the extensions, this specifies which to send. Use (0) to get the first one.
a pointer to a structure to hold the name (may be null)
initially holds the size of buf
will be non−zero if the extension is marked as critical
This function will return the extension specified by the OID in the certificate. The extensions will be returned as binary data DER encoded, in the provided buffer.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code is returned. If the certificate does not contain the specified extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
