The granularity of the sampling is shown, but remains statistical
at best. We assume that the time for each execution of a
function can be expressed by the total time for the function
divided by the number of times the function is called. Thus the
time propagated along the call graph arcs to the function's
parents is directly proportional to the number of times that arc
is traversed.
Parents that are not themselves profiled will have the time of
their profiled children propagated to them, but they will appear
to be spontaneously invoked in the call graph listing, and will
not have their time propagated further. Similarly, signal
catchers, even though profiled, will appear to be spontaneous
(although for more obscure reasons). Any profiled children of
signal catchers should have their times propagated properly,
unless the signal catcher was invoked during the execution of the
profiling routine, in which case all is lost.
The profiled program must call "exit"(2) or return normally for
the profiling information to be saved in the gmon.out file.
