``` cpp
|
| 4 |
+
void lock() noexcept;
|
| 5 |
+
```
|
| 6 |
+
|
| 7 |
+
*Effects:* Opens a region of RCU protection.
|
| 8 |
+
|
| 9 |
+
*Remarks:* Calls to `lock` do not introduce a data race [[intro.races]]
|
| 10 |
+
involving `*this`.
|

|

+
``` cpp
|
| 13 |
+
bool try_lock() noexcept;
|
| 14 |
+
```
|
| 15 |
+
|
| 16 |
+
*Effects:* Equivalent to `lock()`.
|
| 17 |
+
|
| 18 |
+
*Returns:* `true`.
|
| 19 |
+
|
| 20 |
+
``` cpp
|
| 21 |
+
void unlock() noexcept;
|
| 22 |
+
```
|
| 23 |
+
|
| 24 |
+
*Preconditions:* A call to `lock` that opened an unclosed region of RCU
|
| 25 |
+
protection is sequenced before the call to `unlock`.
|
| 26 |
+
|
| 27 |
+
*Effects:* Closes the unclosed region of RCU protection that was most
|
| 28 |
+
recently opened. May invoke scheduled evaluations in `*this`.
|
| 29 |
+
|
| 30 |
+
[*Note 1*: If such evaluations acquire resources held across any
|
| 31 |
+
invocation of `unlock` on `*this`, deadlock can occur. — *end note*]
|
| 32 |
+
|
| 33 |
+
*Remarks:* Calls to `unlock` do not introduce a data race involving
|
| 34 |
+
`*this`.
|
| 35 |
+
|
| 36 |
+
[*Note 2*: Evaluation of scheduled evaluations can still cause a data
|
| 37 |
+
race. — *end note*]
