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

Hey BrowserUK, thanks for responding.

1) I was casting to int because it was what I had the first time it worked, and hadn't yet done further testing (disclaimer: I am literally learning C as I go through this process).

2) Yep, I have full intention to ensure that each 'byte' will be < 256 && > -1 or so to speak (ie. a proper uint8_t). This is a piece of a much larger scenario, where I'll be tearing apart the bits and manipulating and in many cases ensuring each bit range is within proper bounds (ie.,eg: are bits 5-4 set correctly) and my lack of understanding of a few things likely had me leave out some items. There will be added checks for everything, but I tried to keep the sample small.

3) See this node for the why. Again, I'm just coming into the C/XS/bitwise world, so I may not be explaining myself correctly. Essentially, that node shares that I'm working on something where I need a dynamic number of bytes incoming, without having to change the underlying C code, specifically because in some cases, I'll just want to pass the data straight through, other times, I'll need/want to perform bitwise operations on it.

Really, I summarized this thread into a single problem, where maybe I should have explained it for what it was... looking for a solution to two separate issues while taking up as little time of others as possible ;)

Use:  <p> text here (a paragraph) </p>

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.
