If the argument _s is non-NULL it is written to the standard error file descriptor prior to the message string, immediately followed by a colon and a space. If the signal number is not recognized (sigaction(2)), the string ``Unknown signal'' is produced. The message strings can be accessed directly through the external array _s_y_s___s_i_g_l_i_s_t, indexed by recognized signal numbers. The external array _s_y_s___s_i_g_n_a_m_e is used similarly and contains short, lower-case abbrevia- tions for signals which are useful for recognizing signal names in user input. The defined variable NSIG contains a count of the strings in _s_y_s___s_i_g_l_i_s_t and _s_y_s___s_i_g_n_a_m_e.
