<P class="first-line-indented"> The boost::execution exception is an exception used by the Execution Monitor to report problems

detected during controlled function run. It intentionally does not allocate any memory to be safe to use in case of lack

of memory.</P>

<P class="first-line-indented"> Note 1: Only uncaught C++ exceptions are treated as errors. If the application catches a
|
|
C++ exception, it will never reach the <A href="execution_monitor.html">boost::execution_monitor</A>.</P>
|
|
<P class="first-line-indented"> Note 2: These errors include UNIX signals and Windows structured exceptions.
|
|
They are often initiated by hardware traps.</P>
|
|
<P class="first-line-indented"> The implementation decides what is a fatal_system_exception and what is just a system_exception.
|
|
Fatal errors are so likely to have corrupted machine state (like a stack overflow or addressing exception) that it is
|
|
unreasonable to continue execution.</P>
