Hello again,


I came up with another question related to the parallel port.
It is possible to get the baseaddress from a location some where in
memory/bios.

Well, i found a piece of code on the faq :

  #include <sys/nearptr.h>
  #include <crt0.h>

  void * MK_FP (unsigned short seg, unsigned short ofs)
  {
    if ( !(_crt0_startup_flags & _CRT0_FLAG_NEARPTR) )
      if (!__djgpp_nearptr_enable ())
        return (void *)0;
    return (void *) (seg*16 + ofs + __djgpp_conventional_base);
  }


How do i call the function above ????
Cause i get 

D:\Program Files\DJGPP\code>gcc hello.c  > outp.txt
hello.c: In function `get_addresses':
hello.c:32: warning: dereferencing `void *' pointer
hello.c:32: void value not ignored as it ought to be
hello.c: In function `main':
hello.c:48: warning: return type of `main' is not `int'

And my the return address is remarkable large but always the same !


grtz

Simon
