CFX_ByteString::LockBuffer() and CFX_WideString::LockBuffer() add complexity and are nearly unused. #144

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
These string types implement ref-counted shared buffers with COW semantics. The 
lock calls set the refcnt to -1, indicating permanent private ownership, which 
then must be tested in lots of places.

CFX_ByteString::LockBuffer is unused.
CFX_WideString::LockBuffer is called in but one place, prior to a string 
replace.
