( #3333=superdoc: print w/replies, xml ) Need Help??
You didn't really understand the first answer you got on the issue: "where did you find inet_aton documented?".

When you call a subroutine, it must be defined somewhere, unless it is a builtin Perl function, like "each" and "print" in your example. In your code, you want to use functions from the module "Socket.pm" - so you have to "use Socket" to make these functions available.

You can tell that inet_aton is not a Perl function simply by checking with man perlfunc or by trying

perldoc -f inet_aton

Of course, if you misspell a function you'll get the same error, but this is not the issue here.

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.
