- should contain a gnutls_x509_crt_t structure
- const char * oid
- holds an Object Identified in null terminated string
- int indx
- In case multiple same OIDs exist in the extensions, this specifies which to send. Use zero to get the first one.
- void * buf
- a pointer to a structure to hold the name (may be null)
- size_t * sizeof_buf
- initially holds the size of buf
- unsigned int * critical
- will be non zero if the extension is marked as critical

The extensions will be returned as binary data DER encoded, in the provided buffer.A negative value may be returned in case of parsing error. If the certificate does not contain the specified extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
