Detailed Description

Wrapper for readers/writer locks that exist within a process.

Constructor & Destructor Documentation

ACE_RW_Thread_Mutex::ACE_RW_Thread_Mutex ( const ACE_TCHAR name = 0,
void *  arg = 0 
)
ACE_RW_Thread_Mutex::~ACE_RW_Thread_Mutex ( void  )
inline

Default dtor.

Member Function Documentation

void ACE_RW_Thread_Mutex::dump ( void  ) const

Dump the state of an object.

int ACE_RW_Thread_Mutex::tryacquire_write_upgrade ( void  )
inline

Conditionally upgrade a read lock to a write lock. This only works if there are no other readers present, in which case the method returns 0. Otherwise, the method returns -1 and sets errno to EBUSY. Note that the caller of this method must already possess this lock as a read lock (but this condition is not checked by the current implementation).
