Hi,

I have found debugging the performance of areaDetector modules hampered by the fact that epicsThreadShow(All) displays opaque pthread_t pointers - which are less than useless information, rather than Linux thread PID's.

Attached is a patch to R3.14.12.3, which (for Linux only) changes epicsThreadShow(All) so that it displays PID's, not pthread_t's. This means you can run epicsThreadShowAll and easily correlate thread CPU usage with the output of top -H.

My only concern is that it may offend some people who don't like the fact that the POSIX osdThread.c file is not strictly POSIX anymore. However, I feel this is far outweighed by increasing the utility of epicsThreadShow(All).

Cheers,
