Every time I call a C-function that uses arguments, I get an exception that causes Perl to quit.
What exception (what's the message you receive)? You need to investigate (maybe fire up Event Viewer, or a debugger).

You might need to make sure that your DLL is compiled with the -MD flag (or whatever perl -V:ccflags reports).

update: also, try enabling Win32::API::DEBUG and edit API.h and #define WIN32_API_DEBUG.

I did some testing, and I get a memory access violation in the perl dll, and I've tracked it down to API.xs line 651         XSRETURN_IV(lReturn);. It happens with Win32-API-0.41 and perl 5.8.4, 5.6.2, 5.8.7, but not 5.8.6, go figure. XSRETURN_IV comes from XSUB.h (official api). You should solicit help from the author and the perl5-porters. Here's the verbatim debug output

(XS)Win32::API::Call: params[0].t=1, .u=137 (XS)Win32::API::Call: parameter 0 (N) is 137 (XS)Win32::API::Call: Calling ApiFunctionInteger() (XS)Win32::API::Call: ApiFunctionInteger returned 138 (XS)Win32::API::Call: freeing memory... (XS)Win32::API::Call: returning to caller. (XS)Win32::API::Call: returning 138.

I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).

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.
