magic is “special” globals used for process information. Take a
look at <sys/magic.h>

And how can i use __qnx_debug_xfer or Where can i get info on it?

I did mention this as undocumented black magic.

It is prototyped in <sys/debug.h>.

I already have seen definitions from <sys/debug.h>.
Unfortunately they have appeared not so understandable as it would be
desirable.
I would be very grateful if you in brief have described an opportunity of
reception of
_magic structure of any process with use of function __ qnx_debug_xfer.

Yours faithfully in expectation of the answer, é×ÁÎ.

The problem is that i don`t understand how to use this function. And it
prototype is not enought informative.

You may get enough info by downlaoding the source for sysmon - look at
reg.c and register.c which use this function.
