Classes
class ost::Mutex
The Mutex class is used to protect a section of code so that at any
given time only a single thread can perform the protected
operation.
class ost::MutexLock
The MutexLock class is used to protect a section of code so that at
any given time only a single thread can perform the protected
operation.
class ost::ThreadLock
The ThreadLock class impliments a thread rwlock for optimal reader
performance on systems which have rwlock support, and reverts to a
simple mutex for those that do not.
class ost::ReadLock
The ReadLock class is used to protect a section of code through a
ThreadLock for read access to the member function.
class ost::WriteLock
The WriteLock class is used to protect a section of code through a
ThreadLock for write access to the member function.
class ost::MutexCounter
The Mutex Counter is a counter variable which can safely be
incremented or decremented by multiple threads.
class ost::AtomicCounter
The AtomicCounter class offers thread-safe manipulation of an
integer counter.
class ost::Conditional
A conditional variable synchcronization object for one to one and
one to many signal and control events between processes.
class ost::Semaphore
A semaphore is generally used as a synchronization object between
multiple threads or to protect a limited and finite resource such
as a memory or thread pool.
class ost::SemaphoreLock
The SemaphoreLock class is used to protect a section of code
through a semaphore so that only x instances of the member function
may execute concurrently.
class ost::Event
The Event class implements a feature originally found in the WIN32
API; event notification.
class ost::Thread
Every thread of execution in an application is created by
instantiating an object of a class derived from the Thread class.
class ost::Cancellation
A class to automatically set the thread cancellation mode of a
member function.
class ost::PosixThread
class ost::ThreadKey
This class allows the creation of a thread context unique pointer
that can be set and retrieved and can be used to create thread
specific data areas for implementing thread safe library
routines.
class ost::TimerPort
Timer ports are used to provide synchronized timing events when
managed under a service thread such as SocketService.
class ost::SysTime
This class is used to access non-reentrant date and time functions
in the standard C library.
