Constructor & Destructor Documentation

LinuxSharedMemoryIPC::LinuxSharedMemoryIPC ( )

inline

Initializes the internal flags

LinuxSharedMemoryIPC::~LinuxSharedMemoryIPC

(

)

Destroys and unlinks shared memory

Member Function Documentation

virtual bool LinuxSharedMemoryIPC::init ( OS_IPC_ARG *  barg = NULL )

virtual

Initializes shared memory with DEFAULT_GROUPNAME case arg is null.

Parameters

barg	Groupname of the shared memory

Returns

TRUE if no error, FALSE otherwise

Implements OS_IPC.

void LinuxSharedMemoryIPC::stop

(

)

unmaps and unlink shared memory

Returns

void

virtual bool LinuxSharedMemoryIPC::update ( int64_t  ml_phoffset, int64_t  ls_phoffset, FrequencyRatio  ml_freqoffset, FrequencyRatio  ls_freqoffset, uint64_t  local_time, uint32_t  sync_count, uint32_t  pdelay_count, PortState  port_state  )

virtual

Updates IPC values.

Parameters

ls_freqoffset	Local to slave frequency offset
local_time	Local time
sync_count	Count of syncs
pdelay_count	Count of pdelays
port_state	Port's state

Returns

TRUE

Implements OS_IPC.
