23 | /* This module uses the libpthdebug.a library provided by AIX 4.3+ for | |
24 | debugging pthread applications. | |
25 | ||
26 | Some name prefix conventions: | |
27 | pthdb_ provided by libpthdebug.a | |
28 | pdc_ callbacks that this module provides to libpthdebug.a | |
29 | pd_ variables or functions interfacing with libpthdebug.a | |
30 | ||
31 | libpthdebug peculiarities: | |
32 | ||
0fe7bf7b MS |
33 | - pthdb_ptid_pthread() is prototyped in <sys/pthdebug.h>, but |
34 | it's not documented, and after several calls it stops working | |
35 | and causes other libpthdebug functions to fail. | |
c11d79f2 | 36 | |
0fe7bf7b MS |
37 | - pthdb_tid_pthread() doesn't always work after |
38 | pthdb_session_update(), but it does work after cycling through | |
39 | all threads using pthdb_pthread(). | |
