  4. /*    Header for the Thread Library Manager compatability layer. The layer provides
  5.     a very similar functional interface to Apple's Thread Manager.
  6.  
  7.     You can use the macros THREAD_MANAGER_AS_THREAD_LIBRARY and THREAD_LIBRARY_AS_THREAD_MANAGER
  8.     to replace one functional interface with the other. For instance, if you have an
  9.     application written using Thread Manager, and you want to try using Thread Library,
  10.     you can just include this header file in all source files that make calls to Thread
  11.     Manager.
  12.  
  13.     Define THREAD_MANAGER_AS_THREAD_LIBRARY as 1 to enable macros that redefine Thread
  14.     Manager function calls to equivalent Thread Library Manager function calls. This
  15.     is the default if you include this file.
  16.     
  17.     Define THREAD_LIBRARY_AS_THREAD_MANAGER as 1 to enable macros that redefine Thread
  18.     Library Manager function calls to equivalent Thread Manager function calls. */
