if there is no free information output by massif, how could
massif-visualizer show the heap memory usage decreased with thinner
color bar if some function call free?
(take the web side sample for example, the color of main in
massif-visualizer will get thinner at the end of UI output)
I cannot see any free information in the ms_print

Originally I thought maybe my question may nedd to modify source or
compile option.
Sorry for sending to 2 mailing lists ^^

BTW, I found the massif output seems only created when program exit.

is there any option or some modifification for valgrind to generate
massif.out in a period of time or by specific event, such as user add
special code in program or press specia button, etc?
Since I am using valgrind to profile a daemon heap usage when it
runing before and after some specific function, but
that mean I have to kill the daemon before and after running function.
And that is quite inconvinent.

thanks for your kind help,
