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.
Parameters
signum
Type:gint
The signal number. See the signal documentation.
Return value
Type:const gchar*
A UTF-8 string describing the signal. If the signal is unknown,
it returns “unknown signal ()”.
