Re: stay away from 'make up two of my own...'
Please educate me. If everyone should use SIGUSR1 and SIGUSR2, how are collisions with other people's usages ameliorated? It seems to me that collisions are more likely if people follow this advice. I would only use SIGUSR1 or 2 since doc's suggest that behavior may be undefined if a signal is not one of "the available signals". But I would not use signals. I view signals as the system's semaphores. A suitable use for SIGUSR might be to advertise that multiprocessing is coming or going. I suggest sockets, unix-domain sockets, semaphores,or pipes as more suitable mechanisms to be considered.
Be well, In reply to Re^2: OT: Re-use system signals or create userland ones
