Member Function Documentation

void ACE_RW_Thread_Mutex::dump ( void   )  const

Dump the state of an object.

Reimplemented from ACE_RW_Mutex.

ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE 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.
