void ACE_RW_Thread_Mutex::dump

void

)

const

Dump the state of an object.

Reimplemented from ACE_RW_Mutex.

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).

Reimplemented from ACE_RW_Mutex.
