## Detailed Description

### template<ACE_SYNCH_DECL> template class ACE_Stream_Tail

Standard module that acts as the head of a ustream.

## Constructor & Destructor Documentation

template<ACE_SYNCH_DECL>
ACE_Stream_Tail<>::ACE_Stream_Tail<> ( | void )

| Construction.

template<ACE_SYNCH_DECL>
ACE_Stream_Tail<>::~ACE_Stream_Tail<> ( | void )

| Destruction.

## Member Function Documentation

template<ACE_SYNCH_DECL>
int ACE_Stream_Tail< ACE_SYNCH_USE >::canonical_flush ( | ACE_Message_Block * mb )`[private]`

template<ACE_SYNCH_DECL>
int ACE_Stream_Tail< ACE_SYNCH_USE >::close ( | u_long flags = 0 )`[virtual]`

| Hook called from when during thread exit and from the default implemenation of <module_closed>. In general, this method shouldn't be called directly by an application, particularly if the <Task> is running as an Active Object. Instead, a special message should be passed into the <Task> via the <put> method defined below, and the <svc> method should interpret this as a flag to shut down the <Task>. Reimplemented from ACE_Task_Base.

template<ACE_SYNCH_DECL>
int ACE_Stream_Tail<>::control ( | ACE_Message_Block * mb )`[private]`

| Performs canonical flushing at the ACE_Stream tail.

template<ACE_SYNCH_DECL>
void ACE_Stream_Tail<>::dump ( | void ) const

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

template<ACE_SYNCH_DECL>
int ACE_Stream_Tail< ACE_SYNCH_USE >::fini ( | void )`[virtual]`

| Terminates object when dynamic unlinking occurs. Reimplemented from ACE_Shared_Object.

template<ACE_SYNCH_DECL>
int ACE_Stream_Tail< ACE_SYNCH_USE >::info ( | ACE_TCHAR ** strp,
| size_t length ) const`[virtual]`

template<ACE_SYNCH_DECL>
int ACE_Stream_Tail< ACE_SYNCH_USE >::init ( | int argc,
| ACE_TCHAR * argv[] )`[virtual]`

| Initializes object when dynamic linking occurs. Reimplemented from ACE_Shared_Object.

template<ACE_SYNCH_DECL>
int ACE_Stream_Tail< ACE_SYNCH_USE >::open ( | void * a = 0 )`[virtual]`

| Hook called to open a Task. can be used to pass arbitrary information into <open>. Reimplemented from ACE_Task_Base.

template<ACE_SYNCH_DECL>
int ACE_Stream_Tail< ACE_SYNCH_USE >::put ( | ACE_Message_Block * mb,
| ACE_Time_Value * tv = 0 )`[virtual]`

| Transfer msg into the queue to handle immediate processing. Reimplemented from ACE_Task_Base.

template<ACE_SYNCH_DECL>
int ACE_Stream_Tail< ACE_SYNCH_USE >::svc ( | void )`[virtual]`

| Run by a daemon thread to handle deferred processing. Reimplemented from ACE_Task_Base.
