+ * pass - Pass phrase for the private key (possibly empty) or NULL if
+ * there is none.
+ * matchty - Info about which certs/keys to return if many are in the file.
+ * keyid - If private key localkeyids friendlynames are to match a
+ * predetermined value, the value to match. This value should
+ * be an octet string.
+ * keyid_len- Length of the keyid byte string.
+ * name_str - If friendlynames are to match a predetermined value, the value
+ * to match. This value should be a NULL terminated string.
+ * pkey - Points to location pointing to the private key returned.
+ * cert - Points to locaiton which points to the client cert returned
+ * ca - Points to location that points to a stack of 'certificate
+ * authority' certs/trust anchors.
+ *
+ * Match based on the value of 'matchty' and the contents of 'keyid'

+ * matches of the requested type. This function only searches the lists of
+ * matching private keys and client certificates. Kinds of matches allowed,
+ * and the order in which they will be checked, are:
+ *
+ * 1) Find the key and/or cert whose localkeyid attributes matches
+ * 'keyid'.
+ * 2) Find the key and/or cert whose friendlyname attributes matches
+ * 'name_str'
+ * 3) Return the first matching key/cert pair found.
+ * 4) Return the last matching key/cert pair found.
+ * 5) Return whatever cert and/or key are available, even unmatching.
+ *
+ * Append to the CA list, the certs which do not have matching private
+ * keys and which were not selected.
+ *
+ * If none of the bits are set, no client certs or private keys will be
+ * returned. CA (aka trust anchor) certs can be.
+ *
+ * Notes: If #3 is selected, then #4 will never occur. CA certs will be
+ * selected after a cert/key pairs are isolated.
+ *
+ * Returns:
+ * < 0 - An error returned. Call ERR_get_error() to get errors information.
+ * Where possible, memory has been freed.
