// 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) {
|
|
...
