Detailed Description

A bi-directional pipe to exchange data between a RT and a non-RT thread.

Examples

Communication/Serial/render.cpp, Gui/frequency-response/render.cpp, Trill/craft-visual/render.cpp, Trill/flex-visual/render.cpp, and Trill/general-settings/render.cpp.

Member Function Documentation

setup()

bool Pipe::setup	(	const std::string &	pipeName = defaultName,
		size_t	size = 65536 * 128,
		bool	newBlockingRt = false,
		bool	newBlockingNonRt = false )

Initialise the Pipe.

Parameters

the	name of the Pipe. Pipes with the same name share data.
the	size of the Pipe. This is the amount of data that can be stored in the pipe. If the pipe is full, writes will fail.
whether	reads at the RT side should be blocking (can be modified later)
whether	reads at the non-RT side should be blocking (can be modified later)

Returns

true on success, false otherwise

Examples

Communication/Serial/render.cpp.

setBlockingRt()

void Pipe::setBlockingRt

(

bool

blocking

)

Set whether reads at the RT side should be blocking

setBlockingNonRt()

void Pipe::setBlockingNonRt

(

bool

blocking

)

Set whether reads at the non-RT side should be blocking

setTimeoutMsRt()

void Pipe::setTimeoutMsRt

(

double

timeoutMs

)

Set timeout for blocking reads at the RT side.

setTimeoutMsNonRt()

void Pipe::setTimeoutMsNonRt

(

double

timeoutMs

)

Set timeout for blocking reads at the non-RT side.

T &

dest

)

Read data from the RT side.

readRt() [2/2]

template<typename T>

ssize_t Pipe::readRt	(	T *	dest,
		size_t	count )

Read data from the RT side.
