Please don't do this; on UNIX, perror() will report the reason for the last
SYSTEM CALL failure, not the reason for failure of a library routine such as
fopen().  Sometimes there is a close relation between these but at other
times there is not, leading to such absurd diagnostics as "Error opening
file: not a tty".
