C++: No Warning for passing value > 255 as parameter to a function requiring "unsigned char"

[Eljay Love-Jensen]

Hi Martin,

Change this...

unsigned char var = 1000;

...to this...

unsigned char var = MakeUnsignedChar(1000);

And add the function:

#include <stdio.h>
#include <stdlib.h>
unsigned char MakeUnsignedCharFromInt(int x)
{
  if(x > 255 || x < 0)
  {
      fprintf(stderr, "Parameter %d out of unsigned char bounds.", x);
      abort();
  }
  return (unsigned char)x;
}

HTH,
