================
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

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