I'm not sure if this is a novice-type question or not, but what's a SIGEMT signal? The 4.3BSD book by Leffler, McKusick, Karels, and Quarterman gave me the most information: "emulate instruction executed." The Bach Book on System V doesn't mention it, and the System V documentation says "EMT instruction." So does the Berkeley documentation, the sun include file <signal.h>, and the System V include file <signal.h> Does anyone know anything about SIGEMT? -- | Duke Robillard | | Internet: rgr@m10ux.att.com | BITNET: rgr%m10ux.uucp@psuvax1 | | UUCP: {backbone!}att!m10ux!rgr | (maybe) |

SIGEMT (Signal Emergency Medical Technician) is generated by a process that was almost, but not quite killed. This can happen if its parent tried to kill it, but a friendly process chased it off. (After an unsuccessful kill, the aggressive process often goes into a deep blue <defunct>.) So, if you ever do a 'kill -9' and the process doesn't die, they may have done a SIGEMT and been rescued by the paramedics. It is generally advised to wipe all the fingerprints off your keyboard, and to hide your shell. After all, a SIGCOP may have also been generated. -- UUCP: ..!uunet!unhd!rg | USPS: Marine Systems Engineering Laboratory BITNET: r_gonzalez at unhh | University of New Hampshire PHONE: (603) 862-4600 | Marine Programs Building FAX: (603) 862-4399 | Durham, NH 03824-3525
