The ppeerrrroorr() function looks up the language-dependent error message
string affiliated with an error number and writes it, followed by a new-
line, to the standard error stream.
If the argument _s_t_r_i_n_g is non-NULL it is prepended to the message string
and separated from it by a colon and a space (`: '). If _s_t_r_i_n_g is NULL
only the error message string is printed.
The contents of the error message string is the same as those returned by
ssttrreerrrroorr() with argument _e_r_r_n_o.

The ppeerrrroorr() function conforms to ANSI C3.159-1989 (``ANSI C'').
