Thread() [1/2]

Thread ( )

default

Create a null thread.

Thread() [2/2]

Thread ( Function< void()> && f, long stackSize = -1 )

explicit

setName()

void setName

(

const char *

name

)

Set the thread's name for debugging

operator bool()

operator bool ( ) const

explicit

Check if this is a non-null thread.

id()

uint64_t id ( )

static

Get an unique ID indentifying the calling thread.

sleep()

void sleep ( double duration )

static

sleepUntil()

void sleepUntil ( double time )

static

blockSignals()

void blockSignals ( const SignalSet & set )

static

Block signals of given set.

unblockSignals()

void unblockSignals ( const SignalSet & set )

static
