Using | in function params??

I have a function that takes flags, it looks like this:

Code:

---

void Something1(en1 flags)
{
    ...
    ...
}

//where en1 is an enum as:
enum en1
{
  FLAG1,
  FLAG2,
  FLAG3,
  FLAG4,
}
//I need to select more than one flag using the bitwise or operator | like that:
Something1(en1(FLAG1 | FLAG3));

---

How can I do that? I tried in the Something1 function an if clause with if (flags & FLAG1) for example, but it didnt work as expected. Any ideas?

Thanks

Something1(FLAG1 | FLAG2);

should do the trick.

Hello? I did that as you see.
My problem lies in the Something1 definition. Here is what I have so far:

Code:

---

void Something1(en1 flags)
{
  if (flags & FLAG1)
      { do something for flag1 }
  if (flags & FLAG2)
    { do something for flag2 }
  etc etc etc..
}

It wont work correctly.

It worked with defined but for some reason it didnt with enum. In the enum, I dont shift, in the defines I do.
Whats going on here?? :S

Oh, it works now.

Uhh, can you explain me why we used those exact values and any other value wont work?

Oh... :)

Also.. Is there a way to combine that with hex numbers like 0x0400 for example? So i would have in an enum:

Code:

---

enum en1
{
  flag1 = 0x0400,
  flag2 = 0x0500,
  flag3 = 1<<flag3
}

---

would that work?

I see. Since I need to use this in a very few situations, I will stick with the shifting thing. Thanks a lot!
