Test Coverage not on whole execution (gcov)

[Fabien Baron]

Thank you for your answer.

But I want to know if it is possible to start the program, to break it
and set a flag (or something like that) to start coverage counter.
Then resume the execution to have a coverage count.

The aim of that is to count the number of line executed when one
special action is done in my software !

 Best Regards,

Fabien
