close()

void RT::OS::xenomaiFifo::close ( )

overridevirtual

Closes the handle stored and prevents reading from the ui side

Implements RT::OS::Fifo.

Definition at line 139 of file fifo_xenomai.cpp.

getCapacity()

size_t RT::OS::xenomaiFifo::getCapacity ( )

overridevirtual

Get the memory capacity of the fifo

Returns

The maximum amount of memory the fifo can hold

poll()

void RT::OS::xenomaiFifo::poll ( )

overridevirtual

Checks whether there is available data to read on the non-rt side

This function is primarily for non-rt threads to wait on available data from the rt thread. It blocks (sleeps) the calling thread until woken by data availability. SHOULD NOT RUN IN REAL TIME!!

Implements RT::OS::Fifo.

Definition at line 122 of file fifo_xenomai.cpp.

Here is the call graph for this function:

read()

int64_t RT::OS::xenomaiFifo::read ( void *  buf, size_t  data_size  )

overridevirtual

Read the data stored in the FIFO written by realtime thread. Must be run from non-rt thread.

Parameters

buf	The buffer where the data from the buffer should be written to
data_size	The size of the data to read from the buffer

Returns

n Number of elements read. Same as size.

Implements RT::OS::Fifo.

Definition at line 100 of file fifo_xenomai.cpp.

readRT()

int64_t RT::OS::xenomaiFifo::readRT ( void *  buf, size_t  data_size  )

overridevirtual

Read the data stored in the FIFO written by non-RT thread. Must be run from realtime thread.

Parameters

buf	The buffer where the data from the buffer should be written to
data_size	The size of the data to read from the buffer

Returns

n Number of elements read. Same as size.

Implements RT::OS::Fifo.

Definition at line 112 of file fifo_xenomai.cpp.

write()

int64_t RT::OS::xenomaiFifo::write ( void *  buf, size_t  data_size  )

overridevirtual

Write to the FIFO storage for the realtime thread. Must be run from non-rt thread.

Parameters

buf	The buffer holding the data to write to the FIFO.
data_size	The size of the data to read from the buffer

Returns

n Number of elements written. Same as size.

Implements RT::OS::Fifo.

Definition at line 106 of file fifo_xenomai.cpp.

writeRT()

int64_t RT::OS::xenomaiFifo::writeRT ( void *  buf, size_t  data_size  )

overridevirtual

Write to the FIFO storage for the non-RT thread. Must be run from realtime thread.

Parameters

buf	The buffer holding the data to write to the FIFO.
data_size	The size of the data to read from the buffer

Returns

n Number of elements written. Same as size.

Implements RT::OS::Fifo.
