August 12, 2016
The following table shows the kernel synchronization functions.
Functions |
Description |
|---|---|
Requests either shared or exclusive access to a reader/writer lock. |
|
Creates a reader/writer lock. |
|
Deletes the specified reader/writer lock object. |
|
Determines whether the calling thread holds a specified reader/writer lock. |
|
Releases either shared or exclusive access to a reader/writer lock. |
|
Creates a named or an unnamed event object. |
|
Creates a named or unnamed mutex object. |
|
Creates a named or unnamed semaphore object. |
|
Releases all resources used by a critical section object that is not owned. |
|
Duplicates an object handle. The duplicate handle refers to the same object as the original handle. Therefore, any changes to the object are reflected through both handles. |
|
Waits for ownership of the specified critical section object. |
|
Initializes a critical section object. |
|
Performs an atomic comparison of the specified values and exchanges the values based on the outcome of the comparison. |
|
Performs an atomic comparison of the specified parameter values and exchanges the values based on the outcome of the comparison. |
|
Decrements the value of the specified 32-bit variable, and checks the resulting value. |
|
Exchanges a pair of 32-bit values. |
|
Increments an Addend variable. |
|
Exchanges a pair of values. |
|
Increments the value of the specified 32-bit variable, and checks the resulting value. |
|
Performs a conditional setting of a variable. |
|
Releases ownership of the specified critical section object. |
|
Opens an existing named event object. |
|
Provides a single operation that sets to signaled the state of the specified event object and then resets it to nonsignaled after releasing the appropriate number of waiting threads. |
|
Releases ownership of the specified mutex object. |
|
Increases the count of the specified semaphore object by a specified amount. |
|
Sets the state of the specified event object to nonsignaled. |
|
Sets the state of the specified event object to signaled. |
|
Tries to enter a critical section without blocking. |
|
Returns when either any one of the specified objects is in the signaled state, or the time-out interval elapses. |
|
Returns when the specified object is in the signaled state or when the time-out interval elapses. |
