/* Define a mutex wrapper object. This wrapper allows us to easily
|
||
|
|
* track whether or not we currently hold the wrapped mutex. If we hold
|
||
|
|
* the mutex when we destroy it, then we first release it.
|

|
|
*
|
||
|
|
* These are specifically for the case where an ERROR_* handler gets
|
||
|
|
* called when we might (or might not) have a mutex held. The
|
||
|
|
* flexthread_mutex_held() function will tell you if your thread
|
||
|
|
* currently holds the given mutex. It's not safe to make any other
|
||
|
|
* comparisons.
