Hi,
In the man page for signal(3), there is a list of valid signal numbers, one of which is called SIGTHR:
32    SIGTHR       terminate process    thread interrupt
However, this signal is not listed in sys/signal.h. Is this signal implemented in the kernel? If not are there plans to?


It's an incorrect man page.

SIGTHR is used as an IPC mechanism to communicate information between threads in compatibility layers in FreeBSD, which is why it's in the man page. It's basically internal use on FreeBSD 5.x and above.

Please file a bug report against the manual page.
