Install the handler using sigaction() with the SA_RESETHAND flag. When the signal is received, the handler will be de-installed; if SIGSEGV is received again, the program will be terminated. The fact that your program received SIGSEGV suggests that one or more variables contain an invalid value. If you attempt to resume execution without fixing the error, you will just get further SIGSEGVs. More generally, if you detect that your program has got into an invalid state, you have two reasonable choices: either give up (i.e. terminate) or correct the problem. Ignoring the problem and hoping that that the program will magically recover isn't going to work. A more realistic approach for programs which need to run continuously would be to run the program from init with the "respawn" option; if the program terminates, init will restart it. -- Glynn Clements <[EMAIL PROTECTED]> - To unsubscribe from this list: send the line "unsubscribe linux-c-programming" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
