title: Unresolved external symbol for imp_fputws, imp_towupper in visual studio
body: <p>I am developing windows program, and got link error :</p>
  
  <pre><code>error LNK2001: unresolved external symbol __imp__wcsicmp
  error LNK2001: unresolved external symbol __imp_fputws
  error LNK2001: unresolved external symbol __imp_towupper
  </code></pre>
  
  <p>It seems like I need wide char version fputs() and toupper(), but I can't find it.</p>
  
  <p>Could someone provide the library name or compile settings that will resolve the link error?</p>
  
  <p>Environment : Win server 2008 + visual studio 2010 pro + WinDDK 7600.16385.1</p>
