Detailed Description

Macro Definition Documentation

debugf

#define debugf

(

...

)

Value:

([&]{ if constexpr (false) { ignoreVarArgs(__VA_ARGS__); } }())

Need an expression that contains parameters for parameter pack Want to avoid linking printf at any optimisation, hence the constexpr if Want an expression not a statement, hence the lambda wrapper

LOGLEVEL_ARGS

#define LOGLEVEL_ARGS

Start of debug printing format arguments – always specify when using DEBUG/INFO/WARN/ERROR

Function Documentation

ignoreVarArgs()

void ignoreVarArgs ( ... )

extern

Note: no #pragma once because we #undefine debugf at the ends of headers to be able to use debugf inside header code
