22 | machine-independent parts of GDB and the ptrace interface (infptrace.c) to | |
23 | provide access to the HPUX user-mode thread implementation. | |
24 | ||
25 | HPUX threads are true user-mode threads, which are invoked via the cma_* | |
26 | and pthread_* (DCE and Posix respectivly) interfaces. These are mostly | |
27 | implemented in user-space, with all thread context kept in various | |
28 | structures that live in the user's heap. For the most part, the kernel has | |
29 | no knowlege of these threads. | |
