Iata si un exemplu:

int main( )
{
  if( strcasecontain( "NewLifeZM.CsBlackDevil.Com [Zombie Plague]", "newLifeZM.CsBlackDevil.Com" ) )
  {
    /*  "NewLifeZM.CsBlackDevil.Com [Zombie Plague]" contains string "newLifeZM.CsBlackDevil.Com" (without quotes) -- ignoring the characters size */
  }

  return 1;
}
