+
+bugprone-undefined-sprintf-overlap
+==================================
+
+Warns if any arguments to the sprintf family of functions overlap with the
+first argument.
+
+.. code-block:: c++
+
+ char buf[20] = {"hi"};
+ sprintf(buf, "%s%d", buf, 0);
+
+C99 and POSIX.1-2001 states that if copying were to take place between objects
+that overlap, the result is undefined.
+
+Options
+-------
+
+.. option:: SprintfRegex
+
+ A regex specifying the sprintf family of functions to match on. By default,
+ this is "(::std)?::sn?printf".
