Detailed Description

RAII guard for TSS_Mutex (POSIX pthread_mutex_t wrapper)

Acquires lock on construction, releases on destruction. Guards against use-after-lock and missing unlock via RAII discipline. Safe for exception-based unwinding in C++.

Constructor & Destructor Documentation

FACE::TSS::TssMutexGuard::TssMutexGuard ( TSS_Mutex *  mutex, bool  initialized  )

inline

Attempt to acquire lock on construction.

Parameters:

mutex	Pointer to TSS_Mutex (may be NULL)
initialized	Whether the mutex has been initialized

FACE::TSS::TssMutexGuard::~TssMutexGuard ( )

inline

Release lock on destruction (if acquired)

Member Function Documentation

bool FACE::TSS::TssMutexGuard::locked ( ) const

inline

Check whether lock was successfully acquired.

Returns:

true if lock is held, false otherwise

void FACE::TSS::TssMutexGuard::unlock ( )

inline

Manually release the lock before destruction.

Safe to call multiple times; subsequent calls are no-ops.

bool FACE::TSS::TssMutexGuard::relock ( )

inline

Re-acquire the lock after a prior unlock().

Returns:

true if the lock was successfully re-acquired.
