gnutls_x509_crt_get_extension_oid - API function
int gnutls_x509_crt_get_extension_oid(gnutls_x509_crt_t cert, unsigned indx, void * oid, size_t * oid_size);
- gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t type
- unsigned indx
Specifies which extension OID to send. Use (0) to get the first one.
- void * oid
a pointer to a structure to hold the OID (may be null)
- size_t * oid_size
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 provided buffer.
The oid returned will be null terminated, although oid_size will not
account for the trailing null.
On success, GNUTLS_E_SUCCESS
(0) is returned,
otherwise a negative error code is returned. If you have reached the
last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE
will be returned.
