Using | in function params??

[aker_y3k]

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

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:

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:

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!
