ACE_TSS_Keys Class Reference

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. More...

#include <OS.h>

List of all members.

Public Methods

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

int 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.

int 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 had already been cleared, 0 if not.


Private Types

enum  { ACE_WORDS = (ACE_DEFAULT_THREAD_KEYS - 1) / ACE_BITS_PER_WORD + 1 }

Private Attributes

u_long key_bit_words_ [ACE_WORDS]
 Bit flag collection. A bit value of 1 indicates that the key is in use by this thread.


Static Private Methods

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.


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.
