Member Function Documentation

ClearPointer()

void Linux::LinuxThreadLocalData::ClearPointer ( IndexT slot )

static

clear pointer (must only be called after SetPointer)

Clear thread-local pointer for a slot.

GetPointer()

void * Linux::LinuxThreadLocalData::GetPointer ( IndexT slot )

static

get thread local pointer value

Get a thread-local pointer for a slot.

GetThreadLocalTable()

void ** Linux::LinuxThreadLocalData::GetThreadLocalTable ( )

staticprivate

get pointer to thread locale data table, create table if this is the first call for this thread

Allocates a new thread-specific data block and sets it as thread-local data.

This is called from SetPointer(), GetPointer() and the other accessor functions.

RegisterSlot()

IndexT Linux::LinuxThreadLocalData::RegisterSlot ( )

static

register a new slot, this is usually called from the main thread

Register a new slot in the thread-locale table.

This is usually called once from the main-thread per thread-local object.

SetPointer()

void Linux::LinuxThreadLocalData::SetPointer ( IndexT slot, void * ptr )

static

set thread local pointer value (must only be called once)

Set a thread-local pointer for a slot.

This method must only be called once per thread.

SetupMainThread()

void Linux::LinuxThreadLocalData::SetupMainThread ( )

static

setup the object from the main thread (call from SysFunc::Setup())

This method must be called once from the main thread (usually from SysFunc::Setup().
