| // disabled (as indicated by macro BOOST_NO_EXCEPTIONS). |

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

| /* 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) { |
| ... |
| } |
