Hello, I have read "man 7 signal" in Linux, and there are few sections regarding safe and unsafe system calls to be used inside a signal handler.
As I understand (I hope I'm wrong), memory allocations inside a signal handler is unsafe. Is that true ? Further-more, I wish to reload configuration under SIGHUP (it's a daemon application). What is the safest way in your opinion to do so ? For example let's say we have a configuration files regarding database access. How safe will it be to re-read the settings and close and reopen the connection on SIGHUP ? Another question, is it possible to use exitproc if SIGKILL is sent, or there is nothing I can do at all ? And last question for now, is there a more FPC way to handle such issues ? Thanks, Ido
