NAME

ACE_LOCK_SOCK_Acceptor - Specialize ACE_SOCK_Acceptor to lock around accept;

SYNOPSIS

#include <ace/LOCK_SOCK_Acceptor.h>
template<class ACE_LOCK>
class ACE_LOCK_SOCK_Acceptor : public ACE_SOCK_Acceptor
{
  public:
    int accept (
        ACE_SOCK_Stream &new_stream,
        ACE_Addr *remote_addr = 0,
        ACE_Time_Value *timeout = 0,
        int restart = 1,
        int reset_new_handle = 0
        ) const;
    ACE_LOCK &lock (void);
  protected:
    ACE_LOCK lock_;
};

DESCRIPTION

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.

PUBLIC MEMBERS

int accept (
    ACE_SOCK_Stream &new_stream,
    ACE_Addr *remote_addr = 0,
    ACE_Time_Value *timeout = 0,
    int restart = 1,
    int reset_new_handle = 0
    ) const;

Accept the connection under the control of the ACE_LOCK.

ACE_LOCK &lock (void);

Return a reference to the lock.

PROTECTED MEMBERS

ACE_LOCK lock_;

Type of locking mechanism.
