typedef ACE_Map_Manager<ACE_HANDLE, ACE_POSIX_Asynch_Connect_Result *, ACE_SYNCH_NULL_MUTEX> ACE_POSIX_Asynch_Connect::MAP_MANAGER `[private]`

| true - Connect is registered in ACE_Asynch_Pseudo_Task false - Aceept is deregisted in ACE_Asynch_Pseudo_Task

## Constructor & Destructor Documentation

ACE_POSIX_Asynch_Connect::ACE_POSIX_Asynch_Connect | ( | ACE_POSIX_Proactor * | posix_proactor | ) |

| Constructor.

ACE_POSIX_Asynch_Connect::~ACE_POSIX_Asynch_Connect | ( | void |  | ) | `[virtual]`

| Destructor.

## Member Function Documentation

int ACE_POSIX_Asynch_Connect::cancel | ( | void |  | ) | `[virtual]`

| Cancel all pending pseudo-asynchronus requests Behavior as usual AIO request Reimplemented from ACE_POSIX_Asynch_Operation.

int ACE_POSIX_Asynch_Connect::cancel_uncompleted | ( | bool | flg_notify,
|  | ACE_Handle_Set & | set
| ) | `[private]`

Cancel uncompleted connect operations.

- flg_notify Indicates whether or not we should send notification about canceled accepts. If this is false, don't send notifications about canceled connects. If true, notify user about canceled connects according POSIX standards we should receive notifications on canceled AIO requests.

int ACE_POSIX_Asynch_Connect::close | ( | void |  | ) |

| Close performs cancellation of all pending requests.

int ACE_POSIX_Asynch_Connect::connect | ( | ACE_HANDLE | connect_handle,
|  | const ACE_Addr & | remote_sap,
|  | const ACE_Addr & | local_sap,
|  | int | reuse_addr,
|  | const void * | act,
|  | int | priority,
|  | int | signal_number = `0`
| ) | `[virtual]`

This starts off an asynchronous connect.

- connect_handle will be used for the connect call. If ACE_INVALID_HANDLE is specified, a new handle will be created.

Implements ACE_Asynch_Connect_Impl.

int ACE_POSIX_Asynch_Connect::connect_i | ( | ACE_POSIX_Asynch_Connect_Result * | result,
|  | const ACE_Addr & | remote_sap,
|  | const ACE_Addr & | local_sap,
|  | int | reuse_addr
| ) | `[private]`

ACE_HANDLE ACE_POSIX_Asynch_Connect::get_handle | ( | void |  | ) | const`[virtual]`

| virtual from ACE_Event_Handler Reimplemented from ACE_Event_Handler.

int ACE_POSIX_Asynch_Connect::handle_close | ( | ACE_HANDLE | handle,
|  | ACE_Reactor_Mask | close_mask
| ) | `[virtual]`

| virtual from ACE_Event_Handler Reimplemented from ACE_Event_Handler.

int ACE_POSIX_Asynch_Connect::handle_output | ( | ACE_HANDLE | handle | ) | `[virtual]`

| virtual from ACE_Event_Handler The default action on handle_input() and handle_exception is to return -1. Since that's what we want to do, just reuse them. handle_output(), however, is where successful connects are reported. Reimplemented from ACE_Event_Handler.

int ACE_POSIX_Asynch_Connect::open | ( | const ACE_Handler::Proxy_Ptr & | handler_proxy,
|  | ACE_HANDLE | handle,
|  | const void * | completion_key,
|  | ACE_Proactor * | proactor = `0`
| ) | `[virtual]`

| This belongs to ACE_POSIX_Asynch_Operation. We forward this call to that method. We have put this here to avoid the compiler warnings. Reimplemented from ACE_POSIX_Asynch_Operation.

int ACE_POSIX_Asynch_Connect::post_result | ( | ACE_POSIX_Asynch_Connect_Result * | result,
|  | bool | flg_post
| ) | `[private]`

void ACE_POSIX_Asynch_Connect::set_handle | ( | ACE_HANDLE | handle | ) | `[virtual]`

| virtual from ACE_Event_Handler Reimplemented from ACE_Event_Handler.

## Member Data Documentation

bool ACE_POSIX_Asynch_Connect::flg_open_ `[private]`

ACE_SYNCH_MUTEX ACE_POSIX_Asynch_Connect::lock_ `[private]`

| The lock to protect the result map which is shared. The queue is updated by main thread in the register function call and through the auxillary thread in the asynch pseudo task.

MAP_MANAGER ACE_POSIX_Asynch_Connect::result_map_ `[private]`

| Map of Result pointers that correspond to all the pending connects.
