I want to suspend (pause) a forked process at startup and resume it later on. Is there any way to do that with POSIX or Solaris.

I did it by using a semaphore and a signal handler. To wake up the child, the parent process sends a signal to the child process which in turn posts the semaphore from within the signal handler. The child, which was waiting on that semaphore, then wakes up.
