GLib.strsignal

function strsignal(signum: Number(gint)): String {
    // Gjs wrapper for g_strsignal()
}

Returns a string describing the given signal, e.g. "Segmentation fault". You should use this function in preference to strsignal(), because it returns a string in UTF-8 encoding, and since not all platforms support the strsignal() function.

signum: the signal number. See the `signal` documentation
Returns: a UTF-8 string describing the signal. If the signal is unknown, it returns "unknown signal (<signum>)".
