( #3333=superdoc: print w/replies, xml ) Need Help??

In the first example you're 'passing a reference to the corresponding typeglob. and this is the best way to pass filehandles to or from subroutines, since it has the optical effect of removing the ambiguity of the typeglob'

As for the prototyping question: 'a backslash quoted character signifies that the argument absolutely must start with that character - for example, \@ would require that the function call specify a list as the first argument'.. but then you are specifying a typeglob which is in fact everything.. so you're requiring 'everything' to be the first argument, which is pointless...

the quoted lines are from a book... and I hope it helps a bit.

Update: fixed some typos


He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
