still on times (2) man page

I have another little issue about errors. In the RETURN VALUE section is
written:

On error, (clock_t) -1 is returned, and errno is set appropriately.

but no value for errno is specified.  From what I found digging kernel
sources the only error value returned seems to be EFAULT, if tms address
make fail copy_to_user. Should be specified?


Regards
Simone

Yes, probably better. For 3.39, I added the following:

==
.SH ERRORS
.TP
.B EFAULT
.I tms
points outside the process's address space.

Thank you!
