Answer 1

the precision of time in gprof is 0.00. so maybe your module taking less time (milli sec/micro sec).Hence, it will show 0.00 and no time accumulated.So, run the whole program about 1000/1000000 times so that it will come to seconds.At last, divide obtained time with your looping factor (1000/1000000) and that going to be your processing time. I too faced the same problem and by doing this it gets solved.
