Not enough information.

Are the values token4 =  0 & token5 = 32 the values passed into func(), or the values returned by func()?

Because if those are the values coming out of func(), your C program is broken:

  1. 0 & 95 = 0. (0 & anything == 0)
  2. 32 & 32 = 32. (X & X) always == X
  3. 32 & 128 = 0.
  4. 0 | 32 | 0 = 32.

But if the values you've given are the values going into func(), then as you've only supplied a declaration (was that form ever legal C?), we cannot tell what might come out for those inputs.

Further more, the only way I can interpret that declaration of func(), is that it is expecting a pointer to an unsigned char as its input. And the likelyhood of 0 and 32 being valid pointers is minimal.

In the absence of evidence, opinion is indistinguishable from prejudice.

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 How to display code and escape characters are good places to start.
