| \section{\class{wxCriticalSectionLocker}}\label{wxcriticalsectionlocker}
 | |
| 
 | |
| This is a small helper class to be used with \helpref{wxCriticalSection}{wxcriticalsection} 
 | |
| objects. A wxCriticalSectionLocker enters the critical section in the
 | |
| constructor and leaves it in the destructor making it much more difficult to
 | |
| forget to leave a critical section (which, in general, will lead to serious
 | |
| and difficult to debug problems).
 | |
| 
 | |
| Example of using it:
 | |
| 
 | |
| \begin{verbatim}
 | |
| void Set Foo()
 | |
| {
 | |
|     // gs_critSect is some (global) critical section guarding access to the
 | |
|     // object "foo"
 | |
|     wxCriticalSectionLocker locker(gs_critSect);
 | |
| 
 | |
|     if ( ... )
 | |
|     {
 | |
|         // do something
 | |
|         ...
 | |
| 
 | |
|         return;
 | |
|     }
 | |
| 
 | |
|     // do something else
 | |
|     ...
 | |
| 
 | |
|     return;
 | |
| }
 | |
| \end{verbatim}
 | |
| 
 | |
| Without wxCriticalSectionLocker, you would need to remember to manually leave
 | |
| the critical section before each {\tt return}.

| 
 | |
| Constructs a wxCriticalSectionLocker object associated with given
 | |
| {\it criticalsection} and enters it.

|

| \func{}{\destruct{wxCriticalSectionLocker}}{\void}
 | |
| 
 | |
| Destructor leaves the critical section.
