C++ (boolean)? do if true : do if false;

[sankou]

I'm having an issue in one of my functions. I'm trying to format my if statement using the ? and : because I thinks it looks nicer and makes things more readable. But I keep getting an error.

This is the code:

if(m_search != m_first->prev)
     m_search = m_search->next;
else
     return;

I want it to look like this:

(m_search != m_first->prev) ? m_search = m_search->next : return;

However I get the following error.
1>c:...\projects\program1\linklist.h(155): error C2059: syntax error : 'return'

Are you not allowed to return when using that format? Or am I just writing it wrong?

Oh, and it's a void function by the way.
