====== PROCFS

This is a tiny procfs file system that allows read-only access to a few attributes of a task or thread. This tiny procfs fs file system can be built into the system by enabling::

CONFIG_FS_PROCFS=y

It can then be mounted from the NSH command like like::

nsh> mount -t procfs /proc

Example::

NuttShell (NSH) NuttX-6.31 nsh> mount -t procfs /proc

nsh> ls /proc /proc: 0/ 1/

nsh> ls /proc/1 /proc/1: status cmdline

nsh> cat /proc/1/status Name: init Type: Task State: Running Priority: 100 Scheduler: SCHED_FIFO SigMask: 00000000

nsh> cat /proc/1/cmdline init

nsh> sleep 100 & sleep [2:100] nsh> ls /proc ls /proc /proc: 0/ 1/ 2/

nsh> cat /proc/2/cmdline 0x527420
