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