Detailed Description

Collection of in-use flags for a thread's TSS keys. For internal use only by ACE_TSS_Cleanup; it is public because some compilers can't use nested classes for template instantiation parameters.

Wrapper around array of whether each key is in use. A simple typedef doesn't work with Sun C++ 4.2.

Constructor & Destructor Documentation

ACE_TSS_Keys::ACE_TSS_Keys (  void    )

Default constructor, to initialize all bits to zero (unused).

Member Function Documentation

ACE_SPECIAL_INLINE void ACE_TSS_Keys::find (  const u_int    key, u_int &    word, u_int &    bit )  [static, private]

For a given key, find the word and bit number that represent it.

int ACE_TSS_Keys::is_set (  const ACE_thread_key_t    key )  const

Return whether the specific key is marked as in use. Returns 1 if the key is been marked, 0 if not.

int ACE_TSS_Keys::test_and_clear (  const ACE_thread_key_t    key )

Mark the specified key as not being in use, if it was not already so cleared. Returns 1 if the key had already been cleared, 0 if not.

int ACE_TSS_Keys::test_and_set (  const ACE_thread_key_t    key )

Mark the specified key as being in use, if it was not already so marked. Returns 1 if the had already been marked, 0 if not.
