+.. title:: clang-tidy - modernize-replace-memcpy-by-stdcopy
+
+modernize-replace-memcpy-by-stdcopy
+===================================
+
+Replaces all occurrences of the C ``memcpy`` function by ``std::copy``
+
+Example:
+
+.. code-block:: c++
+
+ /*!
+ * \param destination Pointer to the destination array where the content is
to be copied
+ * \param source Pointer to the source of data to be copied
+ * \param num Number of bytes to copy
+ */
+ memcpy(destination, source, num);
+
+becomes
+
+.. code-block:: c++
+
+ /*!
+ * \param destination Pointer to the destination array where the content is
to be copied
+ * \param source Pointer to the source of data to be copied
+ * \param num Number of bytes to copy
+ */
+ std::copy(source, source + (num / sizeof *source), destination);
+
+Bytes to iterator conversion
+----------------------------
+
+Unlike ``std::copy`` that take an iterator on the last element of the source
array, ``memcpy`` request the number of bytes to copy.
+In order to make the check working, it will convert the size parameter to an
iterator by replacing it by ``source + (num / sizeof *source)``
+
+Header inclusion
+----------------
+
+``std::copy`` being provided by the ``algorithm`` header file, this check will
include it if needed.
+
+Options
+-------
+
+.. option:: IncludeStyle
+
+ A string specifying which include-style is used, `llvm` or `google`. Default
+ is `llvm`.
