Thanks a lot folks.64-bit processors have lm ("long mode") in the flags section of cpuinfo whereas 32-bit processors have not. 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 |
