+ *
+ * @param create_mutex

+ * pplock, and location. It should create a unique mutex for each unique
+ * lockname it is provided, and return the mutex identifier in *pplock. The
+ * location parameter can be used for debugging, as it contains the
+ * compiler-provided __location__ of the call.
+ *
+ * @param destroy_mutex
+ * Destroy a mutex. This function should expect two parameters: plock and
+ * location. It should destroy the mutex associated with the identifier
+ * plock. The location parameter can be used for debugging, as it contains
+ * the compiler-provided __location__ of the call.
+ *
+ * @param lock_mutex
+ * Lock a mutex. This function should expect three parameters: plock,
+ * lock_type, and location. The mutex associated with identifier plock
+ * should be locked if lock_type is 1, and unlocked if lock_type is 2. The
+ * location parameter can be used for debugging, as it contains the
+ * compiler-provided __location__ of the call.
+ *
+ * @param create_tls
+ * Create thread local storage. This function should expect three
+ * parameters: keyname, ppkey, and location. It should allocate an
+ * implementation-specific amount of memory and assign the pointer to that
+ * allocated memory to *ppkey. The location parameter can be used for
+ * debugging, as it contains the compiler-provided __location__ of the
+ * call. This function should return 0 upon success, non-zero upon failure.
+ *
+ * @param destroy_tls
+ * Destroy thread local storage. This function should expect two parameters:
+ * ppkey and location. The ppkey parameter points to a variable containing a
+ * thread local storage key previously provided by the create_tls
+ * function. The location parameter can be used for debugging, as it
+ * contains the compiler-provided __location__ of the call.
+ *
+ * @param set_tls
+ * Set a thread local storage variable's value. This function should expect
+ * three parameters: pkey, pval, and location. The pkey parameter is a
+ * thread local storage key previously provided by the create_tls
+ * function. The (void *) pval parameter contains the value to be placed in
+ * the thread local storage variable identified by pkey. The location
+ * parameter can be used for debugging, as it contains the compiler-provided
+ * __location__ of the call. This function should return 0 upon success;
+ * non-zero otherwise.
+ *
+ * @param get_tls
+ * Retrieve a thread local storage variable's value. This function should
+ * expect two parameters: pkey and location. The pkey parameter is a thread
+ * local storage key previously provided by the create_tls function, and
+ * which has previously been used in a call to the set_tls function to
+ * initialize a thread local storage variable. The location parameter can be
+ * used for debugging, as it contains the compiler-provided __location__ of
