Parameter error in Main

[Lettin03]

My main gives compiles an error

void schrijfOutput( char nummer, char waarde );
char leesOutput( char nummer, unsigned char* ddr );
char leesRX( unsigned char* ddr );
void leesRegister( unsigned char* Register )

int main( int argc, char** argv )
{
  unsigned char ddr[4];
  leesRegister( ddr );
  
  while( !leesOutput( 1, ddr ) ) // Blijft in de lus zolang uitvoer 1 niet waar is
  {
    usleep( 100 );
    leesRegister( ddr );
  }
}

The error that appears is

E4092C: both separate parameter declaration and parameter list declaration are used

Though a function is defined with a prototype declaration, non-prototype parameters are
also declared. The separate parameter declaration is not needed.

I can't fix this error, maybe someone can see it?

[laserlight]

The global main function should not have a prototype. Why not provide the smallest and simplest program that demonstrates the compile error?

[matsp]

void schrijfOutput( char nummer, char waarde );
char leesOutput( char nummer, unsigned char* ddr );
char leesRX( unsigned char* ddr );
void leesRegister( unsigned char* Register );

Perhaps a missing semicolon, added above?

Oh yes I see, thats a bit stupid of me. It doesn't give the error anymore, thank you for watching and the advice!
