interprocess - C++ Using files / semaphors to lock step processes / overhead-should I do this at all -

-

i have process a. has various scripts s1, s2, s3, s4, s5.

previously process merely calls script functions. s1->tick(currenttime).

however, standardize sandboxing of these scripts , move them external processes.

my question is:

  1. what best portable c++ (linux/osx/win32) method signal subprocesses new tick dataset available.

  2. what best portable c++ way make data available.

for instance, perhaps write data shared memory area (writable primary process) , have sub processes read memory area?

would faster having sort inter process communication?
