+# This is the configuration file for the PVS-Studio plugin for Visual Studio:
+# https://www.viva64.com/en/pvs-studio/
+#
+# This file can be used to suppress false positives in macros, annotate specific functions,
+# and so on. See the following documentation sections for details:
+#  * Suppression of false alarms          - https://www.viva64.com/en/m/0017/
+#  * Additional diagnostics configuration - https://www.viva64.com/en/m/0040/
+#
+# For instance, you can use this file to specify an alias for a system function.
+# Sometimes projects use custom implementations of certain system functions such as memcpy,
+# malloc, and so on. In this case, the analyzer will not be able to recognize their
+# behavior as that of their standard counterparts. Using the V_FUNC_ALIAS annotation,
+# you can specify which custom functions correspond to which system ones. Comment format:
+#   //V_FUNC_ALIAS, implementation:sysf, function:f, namespace:ns, class:c
+#
+# For example:
+#   //V_FUNC_ALIAS, implementation:memcpy, function:MyMemCpy
+#
+# Now the analyzer will process calls to the MyMemCpy function in the same way it processes
+# calls to memcpy. For example, the following code will trigger the V512 warning:
+#   int buf[] = { 1, 2, 3, 4 };
+#   int out[2];
+#   MyMemCpy (out, buf, 4 * sizeof(int)); // Warning!
+#
+# You can also use this file to suppress warnings on lines that contain a specific
+# character sequence. This option is typically useful for mass suppression of warnings
+# triggered by a certain macro.
+# //-V:TEST_MACRO:1001, 105, 201
+# This comment turns off the warnings V105, V201, and V1001 for the line where the macro
+# TEST_MACRO is used.
+#
+# The # character is considered a comment-introducing character in .pvsconfig files.
+#
+# As already mentioned, all these and other settings are described in detail in the
+# documentation sections the links to which are given at the beginning of this document.
