read() and IO:File->read() error

[Mark H. Siffer]

I have a file I am reading and when I get to a certain point read() and
IO::File->read() return undef. I know I have not reached EOF. Is there
anywhere I can find out why it can't read() or trap an error?

Thanks in advance

how do you know (better than read()) that you have not reached EOF?

and actually if you rtfm carefully, EOF is marked with a 0 return, undef
means an error. so if you really get undef (check with defined) print $!
and see what the error is.
