( #3333=superdoc: print w/replies, xml ) Need Help??
Ah, is it an absolute rule not to use open with sysread/syswrite ?
The reason I ask is that i've had no obvious problems before using something like :

open(HANDLE,"+>$name") or die $!;


Then say a four way select() & sysread() until sysread returns 0. Same can be said for syswrite() but without the select() and zero byte check.

I'm aware that print and read are buffered, but i'm aware of little more than that ;-)

To conclude, i reckon i will implement what was first decided on Sunday, and that is using sysread() to fill up the target scalar, it has been interesting however to have seen the other options, TMTOWTDI indeed.

regards,

Isaac.

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).
