 *   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

 *
 * @param get_tls

 *   expect two parameters: pkey and location. The pkey parameter is a thread
 *   local storage key previously provided by the create_tls function, and
