|
|
* @brief Specialize ACE_SOCK_Acceptor to lock around <accept>;
|
|
*
|
|
* This class is necessary since some OS platforms (e.g.,
|
|
* Solaris 2.5) do not allow multiple threads/processes to
|
|
* simultaneously call <accept> on the same listen-mode
|
|
* port/socket. Thus, we need to protect against multiple
|
|
* concurrent accesses by using the appropriate type of lock.
