Yeah but it does not change the outcome of the if condition check
here. Non-zero esid will make the condition test pass irrespective
of the value of 'valid'. Yes, valid will be checked inside the code
block to print details, the point was value of valid does not make
any difference to the 'if' condition check in the first place.
Unless I am getting tricked here some how :)
