nice-signal-name

Arguments: signal-number

This function returns a string which is a nice (that is a meaningful and easy to interpret) name for signal-number, which must be an integer. This nice name is operating system dependent.

For example, on Solaris and Linux, (nice-signal-name 1) returns "Hangup". On FreeBSD and macOS, the same thing returns "Hangup: 1". It is possible the return values for an OS will change over time because of OS changes.

If signal-number does not name a valid signal, nil is returned.

The function strsignal is a synonym of this function (its name corresponds to the name of the UNIX library function strsignal()). That library function does not exist on Windows but nice-signal-name and strsignal work on all platforms (using different underlying functionality on Windows).
