syntax problem

[RRosalinda]

could you please help me?
What does this mean?

  ( unHandleStatus & 0x01 ? 1 : 0 )

Where unHandleStatus is an unsigned int

Thanks a lot

See, for example:

Or is it the single & that's puzzling you? That's a bitwise AND operator - see:

It's just a compact way of writing an if-else statement.

See Conditional ternary operator
towards the bottom of this page:
http://www.cplusplus.com/doc/tutorial/operators/

    int x; 
    x =  ( unHandleStatus & 0x01 ? 1 : 0 );

would translate as

    int x;
    if (unHandleStatus & 0x01)
        x = 1;
    else
        x = 0;
