+.Fn X509_STORE_new
+allocates and initializes an empty X.509 certificate store
+and sets its reference count to 1.
+.Pp

+increments the reference count of
+.Fa store
+by 1.
+.Pp
+.Fn X509_STORE_free
+decrements the reference count of
+.Fa store
+by 1.
+If the reference count reaches 0,
+all resources used by the store, including all certificates
+contained in it, are released and
+.Fa store
+itself is freed.
+If
+.Fa store
+is a
+.Dv NULL
+pointer, no action occurs.
+.Sh RETURN VALUES
+.Fn X509_STORE_new
+returns a newly created
+.Vt X509_STORE
+object or
+.Dv NULL
+if an error occurs.
+.Pp
+.Fn X509_STORE_up_ref
+returns 1 for success and 0 for failure.
