should contain a gnutls_x509_crt_t structure
This specifies which OID to return. Use zero to get the first one.
a pointer to a buffer to hold the OID (may be null)
initially holds the size of oid
This function will extract the key purpose OIDs of the Certificate specified by the given index. These are stored in the Extended Key Usage extension (2.5.29.37) See the GNUTLS_KP_* definitions for human readable names.
If oid is null
then only the size will be filled.
GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough, and in that case the *sizeof_oid will be updated with the required size. On success 0 is returned.
