Opens the specified named mutex, if it already exists.
Syntax
Parameters
- name
Returns
An object that represents the named system mutex.
Remarks
The erload:System.Threading.Mutex.OpenExisting method tries to open the specified named system mutex. If the system mutex does not exist, this method throws an exception instead of creating the system object. To create the system mutex when it does not already exist, use one of the Mutex.#ctor(bool, string) constructors that has a name parameter.
Multiple calls to this method that use the same value for name do not necessarily return the same System.Threading.Mutex object, even though the objects that are returned represent the same named system mutex.
This method overload is equivalent to calling the Mutex.OpenExisting(string, System.Security.AccessControl.MutexRights) method overload and specifying System.Security.AccessControl.MutexRights.Synchronize and System.Security.AccessControl.MutexRights.Modify rights, combined by using the bitwise OR operation.
Specifying the System.Security.AccessControl.MutexRights.Synchronize flag allows a thread to wait on the mutex, and specifying the System.Security.AccessControl.MutexRights.Modify flag allows a thread to call the Mutex.ReleaseMutex method.
This method does not request ownership of the mutex.
