NAME¶
SbThreadAutoLock - Simple convenience class for locking access to a function.
SYNOPSIS¶
#include <Inventor/threads/SbThreadAutoLock.h>
Public Member Functions¶
SbThreadAutoLock (SbMutex *mutexptr)
SbThreadAutoLock (SbThreadMutex *mutexptr)
~SbThreadAutoLock ()
Protected Attributes¶
SbMutex * mutex
SbThreadMutex * recmutex
Detailed Description¶
Simple convenience class for locking access to a function.
This class provides a simple convenience mechanism for automatically locking access to a function that is not re-entrant.
Usage example:
void
myfunction(void)
{
SbThreadAutoLock lock(aMutexPtr);
// [other code]
}
In the class constructor, SbMutex::lock() is called on the mutex, and when the function exits (this is the convenience part) the destructor will automatically be invoked, calling SbMutex::unlock() on the same mutex.
Constructor & Destructor Documentation¶
SbThreadAutoLock::SbThreadAutoLock (SbMutex * mutex) [inline]¶
The constructor calls SbMutex::lock() on mutex.
SbThreadAutoLock::SbThreadAutoLock (SbThreadMutex * mutex) [inline]¶
The constructor calls SbThreadMutex::lock() on mutex.
SbThreadAutoLock::~SbThreadAutoLock () [inline]¶
The destructor calls unlock() on the mutex passed in as a parameter to the constructor.
Member Data Documentation¶
SbThreadAutoLock::recmutex [protected]¶
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
