Constructor & Destructor Documentation

PrivateMutexContext::PrivateMutexContext ( Mutex::MutexType i_type ) [inline]

PrivateMutexContext::~PrivateMutexContext ( ) [inline]

bool PrivateMutexContext::CheckThisThreadHoldsLock ( ) [inline]

This checks that this thread is the thread holding the lock.

virtual void PrivateMutexContext::Lock ( ) [inline, virtual]

Attempt to lock the mutex.

Returns:
nothing

bool PrivateMutexContext::TryLock ( ) [inline]

TryLock will attempt to take the lock without waiting

void PrivateMutexContext::Unlock ( ) [inline]

Unlock this lock. This combines the conditional lock.

bool PrivateMutexContext::WakeConditional ( )

WakeConditional will awaken the conditional variable (if any)

Returns:
nothing

PrivateConditionalContext* PrivateMutexContext::m_conditional_list

The list of conditional variables that need awakening.

HANDLE PrivateMutexContext::m_os_semaphore

Each mutex has an OS handle to a mutex. This is locked once attempts to attain the spin lock have failed.

unsigned PrivateMutexContext::m_recusion_count

m_recusion_count is the number of times this is locked.

bool PrivateMutexContext::m_recusive

m_recusive indicates that this is a recursive lock

SpinLock PrivateMutexContext::m_spin_lock

m_spin_lock is the basic spin lock - it will fail to get the lock after a small number of cycles.

Task::TaskID PrivateMutexContext::m_task_id

m_task_id is the ID of the task that currently holds this lock.
