hi

our internal log apis support varargs, but do not support <<, it means
that we have to write funciton tracing like this:

printf("%s(%d,%f)", functionName,iCount,dTime);

this need us write format string mannualy each time.

I think the better style looks like:
#define BetterFunctionTrace ....


BetterFunctionTrace(functioName, iCount,dTime);

Is there any way to generate the format string in the compile time
accroding to parameter type and parameter number? i.e.

function1(int,char*,double) => %s(%d,%s,%f);
function2(int,char*,double,unsigned int) => %s(%d,%s,%f,%u);

any idea?

thanks
