process status information

Hi!

How do I get information about other processes? Unlike linux, there is no
/proc/[pid]/stat file, just a file called “as”.

Any help is appreciated.

TIA,

Marcus

Most of our docs have an online index (the exception is the QNX Neutrino
Library Reference). Look in the Utilities Reference’s index under
processes.

Well, I just looked at
http://qdn.qnx.com/support/docs/neutrino_qrp/utilities/keywords-P.html
and all I found was a description of pidin and ps. But I need to get process
status info from within my program :frowning:
Am I just plain dumb, or did I look in the wrong place?

Marcus,
install the migration kit with the package manager, then look at

/usr/src/qssl/nto/mig4nto/qnx_psinfo.c

This is a good example.

You never said you wanted it from within your program.

The Library Reference includes a summary of the functions by category.
Look under “Process environment” and “Process manipulation” to see if
there are any functions that will give you what you want.
