You can change the output template to display the error id from the command line, which is quite neat.
For a Visual Studio format output with error id displayed, add this to your command line:
--template "{file}({line}): {severity} ({id}): {message}"
This will produce output something like this:
s:\src\jpeg.cpp(123): error (bufferAccessOutOfBounds): Buffer access out-of-bounds: abRY
Which you can then suppress by adding the line:
// cppcheck-suppress bufferAccessOutOfBounds
To the previous line in the source file.
