Of course not... just saying that errno varies with each C function and a PITA to translate, so that is why perror() exists. "$!" is already nicely doing the work for us, hence no need for a Perl perror.

From perldoc POSIX:

perror This is identical to the C function "perror()", which outp +uts to the standard error stream the specified message followed b +y ": " and the current error string. Use the "warn()" function an +d the "$!" variable instead, see the warn entry in the perlfunc manpage and the section on "$ERRNO" in the perlvar manpage +.

You said you were new to perror, so I'm just explaining why it exists in C.

    Care to point out where I said I was new to perror? I'm not new to it, and I scrolling back in the thread, I can't find where I erroneously said I did.

        Where does that say I'm new to perror?
