config SYSTEM_POPEN
bool "popen()/pclose() Functions"
default n
select SCHED_WAITPID
depends on NSH_LIBRARY
---help---
Enable support for the popen() and pclose() interfaces.
This will support execution of NSH commands from C code with
pipe communications with the shell.
if SYSTEM_POPEN
config SYSTEM_POPEN_SHPATH
string "Path to shell command"
default "/bin/sh"
depends on SYSTEM_NSH=m || BUILD_KERNEL
---help---
This is the full path to the program in a mounted file system that
implements the system() command. That is, a program that starts the
NSH shell, executes one command (in argv[1]), then exits.
config SYSTEM_POPEN_STACKSIZE
int "Shell stack size"
default DEFAULT_TASK_STACKSIZE
---help---
The size of stack allocated for the shell.
NOTE: I needed to set the stack size quite large to get this example
working on the simulated target (perhaps because of the 64-bit
stack? Or perhaps that is a sneak call into the host libc that I
have not caught). I assume that a smaller stack would be okay on
real hardware, but I have not yet verified that.
config SYSTEM_POPEN_PRIORITY
int "Shell priority"
default 100
---help---
The priority of the shell.
