Reading using a file handle

[awingnut]

I have a function that returns a file handle. I am confused about how to read when an 'open' is not used. I understand reading this way:

open (FILEHANDLE,"myfile.txt");
my $line=<FILEHANDLE>;

In my case I have a function that returns a filehandle:

$pop->get($msgnum,my $fh);
my $line=<$fh>;

Obviously the above is wrong but I can't seem to find how to read it in the docs. Can someone help? TIA.

the function should be assigning and opening the file handle, what does the get function do?

Thanks for the reply. That fucnction opens an email message using POP3 and retuns a file handle for the lines of the email. I need to read those lines. Since the file handle is a returned variable, I don't know how to reference it for read.

are you using Net:OP3?

Yes and I don't want to use an array.

Open the Filehandle for writing before calling the get function, and the contents of the message will be written to the filehandle.

You'll then have to reset the file pointer to start of file, before you can read what was written. You can do this using seek, but the quickest/cleanest way would be to close the file and reopen it for input as opposed to output
