Detailed Description
Provide an adapter that transforms various types of signal handlers into the scheme used by the ACE_Reactor.
Member Enumeration Documentation
◆ anonymous enum

Is this an external handler or an ACE handler?
| Enumerator | |
|---|---|
| ACE_HANDLER | We're just wrapping an ACE_Event_Handler. |
| SIG_ACTION | An ACE_Sig_Action. |
| C_FUNCTION | A normal C function. |

Member Function Documentation
◆ handle_signal()
|
overridevirtual |
Called by the ACE_Reactor to dispatch the signal handler.
Reimplemented from ACE_Event_Handler.
◆ sigkey()
| int ACE_Sig_Adapter::sigkey | ( | ) | const |
Returns this signal key that's used to remove this from the ACE_Reactor's internal table.
Member Data Documentation
◆ ACE_ALLOC_HOOK_DECLARE
| ACE_Sig_Adapter::ACE_ALLOC_HOOK_DECLARE |
◆ eh_
|
private |
This is an ACE event handler.
◆ sa_
|
private |
This should be a union, but C++ won't allow that because the ACE_Sig_Action has a constructor. This is an external handler (ugh).
◆ sig_func_
|
private |
This is a normal C function.
◆ sigkey_
|
private |
Key for this signal handler (used to remove it).
◆
| enum { ... } ACE_Sig_Adapter::type_ |
Is this an external handler or an ACE handler?
