Variable Documentation

s_CTLCtxLock

CSafeStatic<CRWLock> s_CTLCtxLock(CSafeStaticLifeSpan::eLifeSpan_Long) ( CSafeStaticLifeSpan::eLifeSpan_Long  )

static

Static lock which will guard all thread-unsafe operations on most ctlib contexts and a handful of ctlib-scale operations such as cs_init and cs_ctx_*.

It is added because several CTLibContext classes can share one global underlying context handle, so there is no other way to synchronize them but some global lock. Use of non-global context handles considered to be very rare so the impact on using it through global lock can be treated as insignificant.
