Where is just the OS Source?#

• Kernel and Process Manager /services/system
• But included in our source tree, /trunk , are OS-related components we don't normally think of being part of the QNX OS: libraries, filesystems, services and utilities

Where are the good bits?#

The operating system (remember, by "operating system" we mean kernel and procnto) is comprised of the following pieces, each described on its own page:

Kernel#

Guide	Code
The Kernel Source Guide	/services/system/ker

Proc (aka the Process Manager and occasionally procnto)#

This provides the "process management" aspects of the system, including virtual memory and pathname management. It is the special process #1 multi-threaded server and is OS comprised of:

Guide	Code
The Memory Manager	/services/system/memmgr
The Path Manager	/services/system/pathmgr
The Process Manager	/services/system/procmgr and /services/system/proc

Public headers for the above, plus the kernel, are stored in /services/system/public.

The C Library (aka the clib or the glue)#

Guide	Source
Anatomy of the C Library	lib/c
