DESCRIPTION

number passed in the argument
sig.
The string can be used only until the next call to
strsignal().
The array
sys_siglist
holds the signal description strings
indexed by signal number.
The
strsignal()
function should be
used if possible instead of this array.

string, or an unknown signal message if the signal number is invalid.
On some systems (but not on Linux), NULL may instead be
returned for an invalid signal number.
