title: Passing one va_list as a parameter to another
body: <p>I'm creating an application using the fastcgi library, and their method of printing is a little verbose. I'm trying to wrap their fprintf function in my own method:</p>
  
  <p>I would like to turn</p>
  
  <blockquote>
    <p>FCGX_FPrintF(out, char* fmt, ...);</p>
  </blockquote>
  
  <p>into</p>
  
  <blockquote>
    <p>write(char* strFormat, ...);</p>
  </blockquote>
  
  <p>I've found the magic of va_list but can't find an easy way to pass va_list values into their fprintf function. Is there a way to do this? I know vsprintf and vprintf exist so it must be harder than I imagine it is.</p>
  
  <p>If all else fails, I'll just overload a write function</p>
