- * Revised by Keith Whitwell

- * DOCUMENTATION
- *
- * This thread module exports the following types:
- *   _glthread_TSD     Thread-specific data area
- *   _glthread_Thread  Thread datatype
- *   _glthread_Mutex   Mutual exclusion lock
- *
- * Macros:
- *   _glthread_DECLARE_STATIC_MUTEX(name)   Declare a non-local mutex
- *   _glthread_INIT_MUTEX(name)             Initialize a mutex
- *   _glthread_LOCK_MUTEX(name)             Lock a mutex
- *   _glthread_UNLOCK_MUTEX(name)           Unlock a mutex
- *
- * Functions:
- *   _glthread_GetID(v)      Get integer thread ID
- *   _glthread_InitTSD()     Initialize thread-specific data
- *   _glthread_GetTSD()      Get thread-specific data
- *   _glthread_SetTSD()      Set thread-specific data
- *
- * If this file is accidentally included by a non-threaded build,
- * it should not cause the build to fail, or otherwise cause problems.
- * In general, it should only be included when needed however.
+ * Thread, mutex, condition var and thread-specific data functions.
