Constructor & Destructor Documentation

cReceiver::cReceiver (  int    Ca, int    Priority, int    NumPids, ...    )

Creates new receiver. Creates a new receiver that requires conditional access Ca and has the given Priority. NumPids defines the number of PIDs that follow this parameter. If any of these PIDs are 0, they will be silently ignored. The total number of non-zero PIDs must not exceed MAXRECEIVEPIDS. Priority may be any value in the range 0..99. Negative values indicate that this cReceiver may be detached at any time (without blocking the cDevice it is attached to). Definition at line 27 of file receiver.c. References ca, device, esyslog, MAXRECEIVEPIDS, pids, and priority.

Member Function Documentation

virtual void cReceiver::Activate (  bool    On )  [inline, protected, virtual]

This function is called just before the cReceiver gets attached to (On == true) or detached from (On == false) a cDevice. It can be used to do things like starting/stopping a thread. It is guaranteed that Receive() will not be called before Activate(true). Reimplemented in cRecorder, and cTransfer. Definition at line 35 of file receiver.h. Referenced by cDevice::AttachReceiver(), and cDevice::Detach().

void cReceiver::Detach (  void    )  [protected]

Definition at line 76 of file receiver.c. References cDevice::Detach(), and device. Referenced by ~cReceiver(), cRecorder::~cRecorder(), and cTransfer::~cTransfer().

virtual void cReceiver::Receive (  uchar *    Data, int    Length )  [protected, pure virtual]

This function is called from the cDevice we are attached to, and delivers one TS packet from the set of PIDs the cReceiver has requested. The data packet must be accepted immediately, and the call must return as soon as possible, without any unnecessary delay. Each TS packet will be delivered only ONCE, so the cReceiver must make sure that it will be able to buffer the data if necessary. Implemented in cRecorder, and cTransfer.
