Hi Michael,
I haven't found any of the constants (PFM_*) used by this function in
glibc. Also not in the kernel, although in the kernel I found other
PFM_* constants different from the ones in the manual page.
I checked that this page hasn't received any patches in a very long time
(except for "Various pages" patches), so I suspect it may be out of date.
Also, does <perfmon.h> really exist? I couldn't find it either.
Cheers,
Alex
