Getting The Processor Family

[James Parsons]

Is there a macro for retrieving the CPU Family(x86, PPC, ARM). I have seen such a method for detecting OS.

#IFDEF _WIN64
  doThat();
#ENDIF 

Is there a similar method for CPU detection?

There is no standard and compatible mode to do that. You will need to detect compiler first ( http://sourceforge.net/p/predef/wiki/Compilers/ ) and then cpu architecture:
