Member Function Documentation

int XrdSys::IOEvents::PollPort::AllocMem ( void **  memP, int  slots  )

static

void XrdSys::IOEvents::PollPort::Begin ( XrdSysSemaphore *  syncp, int &  rc, const char **  eTxt  )

protectedvirtual

Start the polling event loop. An implementation must be supplied. Begin() is called via the internal BootStrap class from a new thread.

Implements XrdSys::IOEvents::Poller.

References XrdSysSemaphore::Post().

timespec_t* XrdSys::IOEvents::PollPort::BegTO ( timespec_t &  theTO )

void XrdSys::IOEvents::PollPort::Dispatch ( Channel *  cP, int  pollEv  )

private

void XrdSys::IOEvents::PollPort::Exclude ( Channel *  cP, bool &  isLocked, bool  dover = 1  )

protectedvirtual

Remove a channel to the poll set. An implementation must be supplied. The channel is locked when this method is called but must be unlocked by the method if a command is sent to the poller thread and isLocked set to false.

Implements XrdSys::IOEvents::Poller.

References XrdSys::IOEvents::Channel::GetFD(), and XrdSys::IOEvents::Poller::PipeData::req.

bool XrdSys::IOEvents::PollPort::Include ( Channel *  cP, int &  eNum, const char **  eTxt, bool &  isLocked  )

protectedvirtual

Add a channel to the poll set. An implementation must be supplied. The channel is locked when this method is called but must be unlocked by the method if a command is sent to the poller thread and isLocked set to false.

Implements XrdSys::IOEvents::Poller.

References XrdSys::IOEvents::Channel::GetEvents(), and XrdSys::IOEvents::Channel::GetFD().

bool XrdSys::IOEvents::PollPort::Modify ( Channel *  cP, int &  eNum, const char **  eTxt, bool &  isLocked  )

protectedvirtual

Modify the event status of a channel. An implementation must be supplied. The channel is locked when this method is called but must be unlocked by the method if a command is sent to the poller thread and isLocked set to false.

Implements XrdSys::IOEvents::Poller.

References XrdSys::IOEvents::Channel::GetEvents(), and XrdSys::IOEvents::Channel::GetFD().

bool XrdSys::IOEvents::PollPort::Process ( )

private

void XrdSys::IOEvents::PollPort::Shutdown ( )

protectedvirtual

Shutdown the poller. An implementation must be supplied. The shutdown method must release any allocated storage and close private file descriptors. The polling thread will have already been terminated and x-thread pipe closed. Warning: the derived destructor must call Stop() and do nothing else!

Implements XrdSys::IOEvents::Poller.

References close(), XrdSysMutex::Lock(), and XrdSysMutex::UnLock().
