Detailed Description

template<class ACE_LOCK>
class ACE_LOCK_SOCK_Acceptor< ACE_LOCK >

Specialize ACE_SOCK_Acceptor to lock around <accept>;.

This class is necessary since some OS platforms 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.

Member Function Documentation

◆ accept()

template<class ACE_LOCK >

int ACE_LOCK_SOCK_Acceptor< ACE_LOCK >::accept	(	ACE_SOCK_Stream &	new_stream,
		ACE_Addr *	remote_addr = 0,
		ACE_Time_Value *	timeout = 0,
		bool	restart = true,
		bool	reset_new_handle = false ) const

Accept the connection under the control of the <ACE_LOCK>.

◆ lock()

template<class ACE_LOCK >

ACE_LOCK & ACE_LOCK_SOCK_Acceptor< ACE_LOCK >::lock ( )

Return a reference to the lock.
