- * _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
