Hello, I'm working on a big project in C code, and I want to profile it so I used gcc with the options -ftest-coverage and -fprofile-arcs, and gcov to analyze the results. It works very well but on the whole project and the whole execution !! My question is : Is it possible to start and stop profiling/coverage during the program execution ? If it is how I can do that ? I'm working with cygwin ! Thank you for your answer .... Fabien
