I want to build a class to use my Sound Blaster and it rest only one
problem:

class Sb
{  .....
   public:
   ....
   void interrupt dsp_int_sb16(__CPPARGS);
   void    DetectIRQ(void);
   ....
};

void interrupt Sb::dsp_int_sb16(__CPPARGS)
{
......
}

void Sb::DetectIRQ(void)
{ ....
  setvect(8+dsp_irq,&Sb::dsp_int_sb16);
  ....
}

The problem is on the setvect...
Error Machin.cpp 465 : Cannot convert 'void (interrupt Sb::*)(...)' to 'void
(interrupt *)(...)'
Error Machin.cpp 465 : Type mistach in parameter '__isr' in call to
'setvect(int,void (interrupt *)(...))'
i tryed with casts operators, but nothing goes...:-<<<
If you already had this problem or if you know how to resolve it, please can
you help me?
Thank you!

  The error message indicates that the compiler cannot convert a pointer to a
class member function into a pointer to a function.  You need to pass the
address of a C function instead of a C++ object member function.  Declare your
dsp_int_sb16() at file scope instead of within Sb.

You need to make dsp_int_sb16() static.
dsp_int_sb16() is currently a method of class Sb and therefore requires a
"this" pointer to call it.
