Static Private Member Functions | |
static void | find (const u_int key, u_int &word, u_int &bit) |
For a given key, find the word and bit number that represent it. | |
Private Attributes | |
u_long | key_bit_words_ [ACE_WORDS] |
Wrapper around array of whether each key is in use. A simple typedef doesn't work with Sun C++ 4.2.
ACE_TSS_Keys::ACE_TSS_Keys | ( | void | ) |
Default constructor, to initialize all bits to zero (unused).
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.
u_long ACE_TSS_Keys::key_bit_words_[ACE_WORDS] [private] |
Bit flag collection. A bit value of 1 indicates that the key is in use by this thread.
