Thanks a lot folks.
Adding more detail on this.
Below detail helps to understand CPU architecture.
_*
*__*Finding CPU Arch*_
$ grep flags /proc/cpuinfo | uniq | egrep -o -w "rm|tm|lm"
Under "Flags" section in /proc/cpuinfo, you will find any of the
flags "tm" or
"rm" or "lm"
* rm (Real Mode) means it is a 16 bit processor
* tm (Transparent Mode) means it is a 32 bit processor
* lm (Long Mode) means it is a 64 bit processor
Is this only way to find the processor architecture ????
Any C programming technique apart from using this /proc/cpuinfo detail?
Thanks,
Prabhu
