## Detailed Description

Defines the format and interface for the acceptor side of the local mmap stream.

This class should be modified to prevent user passing a non-localhost endpoint as the acceptor listen point because it doesn't make any sense at all to make the listening endpoint visible (or connectable) anywhere outside of this machine. However, the type of endpoint is left as <ACE_Addr> so we can later changed to use UNIX sockets with mmap stream if so desired. (Currently, using UNIX socket with this class will not work.)

## Member Function Documentation

ASYS_INLINE int ACE_MEM_Acceptor::accept | ( | ACE_SOCK_Stream & | new_stream,
|  | ACE_Accept_QoS_Params | qos_params,
|  | ACE_Addr * | remote_addr = 0,
|  | ACE_Time_Value * | timeout = 0,
|  | int | restart = 1,
|  | int | reset_new_handle = 0
| ) | const`[protected]`

Accept a new <ACE_SOCK_Stream> connection using the QoS information in <qos_params>. A <timeout> of 0 means block forever, a <timeout> of {0, 0} means poll. <restart> == 1 means "restart if interrupted," i.e., if errno == EINTR. Note that <new_stream> inherits the "blocking mode" of <this> <ACE_SOCK_Acceptor>, i.e., if <this> acceptor factory is in non-blocking mode, the <net_stream> will be in non-blocking mode and vice versa.

Reimplemented from ACE_SOCK_Acceptor.

ASYS_INLINE int ACE_MEM_Acceptor::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`[protected]`

Accept a new <ACE_SOCK_Stream> connection. A <timeout> of 0 means block forever, a <timeout> of {0, 0} means poll. <restart> == 1 means "restart if interrupted," i.e., if errno == EINTR. Note that <new_stream> inherits the "blocking mode" of <this> <ACE_SOCK_Acceptor>, i.e., if <this> acceptor factory is in non-blocking mode, the <net_stream> will be in non-blocking mode and vice versa.

Reimplemented from ACE_SOCK_Acceptor.

int ACE_MEM_Acceptor::accept | ( | ACE_MEM_Stream & | new_ipc_sap,
|  | ACE_MEM_Addr * | remote_addr = 0,
|  | ACE_Time_Value * | timeout = 0,
|  | int | restart = 1,
|  | int | reset_new_handle = 0
| ) |

| Accept a new data transfer connection.

void ACE_MEM_Acceptor::dump | ( | void |  | ) | const

| Dump the state of an object. Reimplemented from ACE_SOCK_Acceptor.

ASYS_INLINE int ACE_MEM_Acceptor::get_local_addr | ( | ACE_MEM_Addr & |  | ) | const

| Return the local endpoint address in the referenced <ACE_Addr>. Returns 0 if successful, else -1.

ASYS_INLINE void ACE_MEM_Acceptor::init_buffer_size | ( | off_t | bytes | ) |

| Change the initial MMAP buffer size (in bytes) of the MEM_Stream this MEM_Acceptor creates.

ASYS_INLINE ACE_MEM_SAP::MALLOC_OPTIONS & ACE_MEM_Acceptor::malloc_options | ( | void |  | ) |

| Accessor to the mmap options. This method has been deprecated.

ASYS_INLINE void ACE_MEM_Acceptor::mmap_prefix | ( | const ACE_TCHAR * | prefix | ) |

ASYS_INLINE const ACE_TCHAR * ACE_MEM_Acceptor::mmap_prefix | ( | void |  | ) | const

| Accessor/mutator of mmap filename prefix. By default, the <mmap_prefix_> is not set and the mmap filename is ${(TMP|TEMP)}//ACE_MEM_Acceptor_(port-number)_(&stream), otherwise, it is <mmap_prefix_>_(port-number)_(&stream), <mmap_prefix_> should include _absolute_ path so the connector within the same host can located the mmap file. Example: /tmp/mmapfile.

ASYS_INLINE int ACE_MEM_Acceptor::open | ( | const ACE_Addr & | local_sap,
|  | ACE_Protocol_Info * | protocolinfo,
|  | ACE_SOCK_GROUP | g,
|  | u_long | flags,
|  | int | reuse_addr,
|  | int | protocol_family,
|  | int | backlog = ACE_DEFAULT_BACKLOG,
|  | int | protocol = 0
| ) | `[protected]`

| Initialize a passive-mode QoS-enabled acceptor socket. Returns 0 on success and -1 on failure. Reimplemented from ACE_SOCK_Acceptor.

int ACE_MEM_Acceptor::open | ( | const ACE_Addr & | local_sap,
|  | int | reuse_addr = 0,
|  | int | protocol_family = PF_INET,
|  | int | backlog = ACE_DEFAULT_BACKLOG,
|  | int | protocol = 0
| ) | `[protected]`

| Initialize a passive-mode BSD-style acceptor socket (no QoS). <local_sap> is the address that we're going to listen for connections on. If <reuse_addr> is 1 then we'll use the <SO_REUSEADDR> to reuse this address. Returns 0 on success and -1 on failure. Reimplemented from ACE_SOCK_Acceptor.

int ACE_MEM_Acceptor::open | ( | const ACE_MEM_Addr & | local_sap,
|  | int | reuse_addr = 0,

| ) |

| Initialize a passive-mode BSD-style acceptor socket (no QoS). <local_sap> is the address that we're going to listen for connections on. If <reuse_addr> is 1 then we'll use the <SO_REUSEADDR> to reuse this address. Returns 0 on success and -1 on failure.

ASYS_INLINE void ACE_MEM_Acceptor::preferred_strategy | ( | ACE_MEM_IO::Signal_Strategy | strategy | ) |

| Set the preferred signaling strategy.

ASYS_INLINE ACE_MEM_IO::Signal_Strategy ACE_MEM_Acceptor::preferred_strategy | ( | void |  | ) | const

| Perform operations that must occur after <ACE_OS::accept> is called.
