Member Function Documentation

void ACE_RW_Thread_Mutex::dump void    const
 

Dump the state of an object.

Reimplemented from ACE_RW_Mutex.

Definition at line 886 of file Synch.cpp.

References ACE_RW_Mutex::dump.

00887 {
00888 // ACE_TRACE ("ACE_RW_Thread_Mutex::dump");
00889   ACE_RW_Mutex::dump ();
00890 }

int ACE_RW_Thread_Mutex::tryacquire_write_upgrade void   
 

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).

Reimplemented from ACE_RW_Mutex.
