// This file contains helper macros used when exception support may be

// disabled (as indicated by macro BOOST_NO_EXCEPTIONS).

//

// Before picking up these macros you may consider using RAII techniques

// to deal with exceptions - their syntax can be always the same with 

// or without exception support enabled.

//



/* Example of use:



void foo() {

  BOOST_TRY {

    ...

  } BOOST_CATCH(const std::bad_alloc&) {

      ...

      BOOST_RETHROW

  } BOOST_CATCH(const std::exception& e) {

      ...

  }

  BOOST_CATCH_END

}



With exception support enabled it will expand into:



void foo() {

  { try {

    ...

  } catch (const std::bad_alloc&) {

      ...

      throw;

  } catch (const std::exception& e) {

      ...

  }

  }

}



With exception support disabled it will expand into:



void foo() {

  { if(true) {

    ...

  } else if (false) {

      ...

  } else if (false)  {

      ...

  }

  }

}
