Would it suffice to trigger this from an environment variable? If the function in question is in a shared library, an LD_PRELOAD shim could provide this information. A stub could capture time, pid, function args then proxy onto the original function (and capture time+return value on the way back if desired). I think Solaris truss allows this (truss -u), with pattern matching on library and function name. Automating the LD_PRELOAD shim so it has a better UI than writing your own stub by hand shouldn't be too tricky. Is that what you want/need or do you think it would throw the timings off too much? jb _______________________________________________ Performance-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/performance-list
