Detailed Description

RAII guard engaging the same lock used by the open helpers.

Use this around code that constructs TFile objects directly instead of going through OpenForReading() / OpenForWriting(), so that hand-rolled opens serialise against the helpers rather than racing them.

The guard is a no-op when thread-safe mode is off, and the underlying mutex is recursive, so nesting a guard inside a helper call is safe.

Note

Non-copyable. The engaged/idle decision is made at construction, so a guard created before SetThreadSafe(kTRUE) stays idle for its lifetime.
