| 25 | |
| 26 | HPUX threads are true user-mode threads, which are invoked via the cma_* |
| 27 | and pthread_* (DCE and Posix respectivly) interfaces. These are mostly |
| 28 | implemented in user-space, with all thread context kept in various |
| 29 | structures that live in the user's heap. For the most part, the kernel has |
| 30 | no knowlege of these threads. |
