ReleaseMutex
The ReleaseMutex function releases ownership of the specified mutex object.
BOOL ReleaseMutex(
HANDLE hMutex
| // handle of mutex object
| );
|
|
Parameters
hMutex
Identifies the mutex object. The CreateMutex or OpenMutex function returns this handle.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
The ReleaseMutex function fails if the calling thread does not own the mutex object.
A thread gets ownership of a mutex by specifying a handle of the mutex in one
of the wait functions. The thread that creates a mutex object can also get immediate ownership
without using one of the wait functions. When the owning thread no longer needs to
own the mutex object, it calls the ReleaseMutex function.
While a thread has ownership of a mutex, it can specify the same mutex in
additional wait-function calls without blocking its execution. This prevents a
thread from deadlocking itself while waiting for a mutex that it already owns.
However, to release its ownership, the thread must call ReleaseMutex once for each time that the mutex satisfied a wait.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
