Comments:
Used to control locks on RWLockC for exception safe resoures locking. It is the users responsability to ensure that the RWLockC remains valid for the lifetime of any RWLockHoldC instance.

SMALL OBJECT

RWLockHoldC(const RWLockC & m,BooleanT readOnly = true,BooleanT tryOnly = false)

Create a lock on a rwlock.
This may not seem like a good idea, but it allows otherwise constant functions to lock out other accesses to data without undue faffing.

void Unlock()

~RWLockHoldC()

Create a lock on a rwlock.

void LockRd()

relock for read

void LockWr()

relock for write

BooleanT IsReadLocked() const

Test if safe for reading.
This will return true if either a write or read lock is inplace.

BooleanT IsWriteLocked() const

Test if safe for writing.
