+SYNOPSIS
+        #include <sys/ tls.h>
+        int *tls_query_connection_info (object ob)
+
+DESCRIPTION
+        If <ob> does not have a TLS connection or if the connection
+        is still being set-up, or if <ob> is not interactive, the efun
+        returns 0.
+
+        If <ob> has a TLS connection, tls_query_connection_info()
+        returns an array that contains some parameters of <ob>'s
+        connection:
+
+          int|string [TLS_CIPHER]: the cipher used
+          int        [TLS_COMP]:   the compression used
+          int        [TLS_KX]:     the key-exchange used
+          int        [TLS_MAC]:    the digest algorithm used
+          int|string [TLS_PROT]:   the protocol used
+
+        To translate these numbers into strings, <tls.h> offers a
+        number of macros:
+
+          TLS_xxx_TABLE: a literal array of strings describing the
+            value in question.
+          TLS_xxx_NAME(x): a macro translating the numeric result
+            value into a string.
+
+          xxx: CIPHER, COMP, KX, MAC, PROT
+
+HISTORY
+        Introduced in LDMud 3.3.474 and following, backported to 3.2.11.
