C++ (Cpp) _STLP_ATOMIC_INCREMENT Examples

Example #1

File: locale.cpp Project: BackupTheBerlios/wl530g-svn

// Takes a reference to a locale::id, and returns its numeric index.
// If no numeric index has yet been assigned, assigns one.  The return
// value is always positive.
static size_t _Stl_loc_get_index(locale::id& id) {
  if (id._M_index == 0) {
#if defined (_STLP_ATOMIC_INCREMENT)
    id._M_index = _STLP_ATOMIC_INCREMENT(&(locale::id::_S_max));
#else
    static _STLP_STATIC_MUTEX _Index_lock _STLP_MUTEX_INITIALIZER;
    _STLP_auto_lock sentry(_Index_lock);
    size_t new_index = locale::id::_S_max++;
    id._M_index = new_index;
#endif
  }
  return id._M_index;
}

Example #2

File: locale.cpp Project: ChunHungLiu/stlport

// Takes a reference to a locale::id, assign a numeric index if not already
// affected and returns it. The returned index is always positive.
