- // 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) {
- ...
- }
- }
- }
