>> _emit 0xF0 0xA2
Is this correct. As I know _emit can define a single byte.

By the way what the function is doing.
Can you please explain.

What OS and what hardware are you using?

BTW your application may not be shure that it's running on specific CPU, even when you reach next line of your C application.

Thanks for the response jkr, but I am confused how am I supposed to use the folowing code snippet..?? Can you please details it a btit more..??
Also if you can let me know how to call a C file from with-in a shell script while your .rpm package is getting installed. This C file would provide the necessary inout to the shell script which would then forward this input to the installing software. Any clue on this...??

Thanks
