By checking the value of waitpid for a possible -1 return, I never "think" I have kids left when I really don't. The -1 force-resets the hash.
Good, I should check for the return value of wait as well. Thanks.
Sorry if I am bothering you about this, but I am missing an information: why do you prefer waitpid to wait? Flexybility? Possibility to make waitpid a non-blocking call? What?
Thanks in advance.
The very nature of Perl to be like natural language--inconsistant and full of dwim and special cases--makes it impossible to know it all without simply memorizing the documentation (which is not complete or totally correct anyway).
