Thread is a light weight process which maintains its own stack and registers but can share the other resources allocated for the process.CMutex and Csemaphore both are used for thread and process synchronisation. CMutex can allow at the most one thread/process to access the resource that also mutually exclusively but Csemaphore can allow the access to the resource to a number of threads/processes simultaneously.

Hi,

  Thread is the smallest set of instructions that can be executed..

   Cmutex and Csemaphore are the ways used for synchronization purpose.

 the difference between the above two is..Cmutex is a single lock where as csemaphore is  a multilock..

Hai,

Thread: is a path Execution of a program....So that the thread having its own stack,and all other resources..

In VC++ we have 4 synchronization Objects.

1)CCriticalSection: This is not aKernal object. using this object you can synchronize one or more threads with in the same process.

2)CMutex

3)CEvent

4)CSemaphore these three are kernal objects

using mutex you can sync two r more threads in the same process or diff process...

 

i hope u get little bit idea abt these objects

thanks & regards

Cmutex is the synchronization object to control access of a resource by multiple applications(one thread of each application to access the resource at a time).

CSemaphore is the synchronization object to control access of a resource by multiple threads of a process. CSemaphore allows to specify the number of threads which can process the resource at the same time.
