Here are some offenders: examples/cc3000/shell.c, examples/nsh/nsh_main.c, examples/nxterm/nxterm_main.c, and examples/pty_test/pty_test.c. It is possible that for some of those, that represents the first call to nsh_consolemain(). But probably not. To give other initialization options, I added nsh_consolechild() which is identical to nsh_consolemain() other than it omits all of the one-time initialization. Of course, you would not get the result that you wanted if nsh_consolechild() were called without nsh_consolemain().

* Name: nsh_consolemain (Normal character device version)
|
|
*
|
|
* Description:
|
|
* This interfaces may be to called or started with task_start to start a
|
|
* single an NSH instance that operates on stdin and stdout. This
|
|
* function does not normally return (see below).
|
|
*
|
|
* This function performs all basic, one-time initialization logic as
|
|
* configured. This includes such things as mounting the romfs /etc/
|
|
* file system and running the initialization script, setting up USB
|
|
* tracing options. It should be spawned only once for this reason.
|
|
*
|
|
* This version of nsh_consolmain() handles generic /dev/console character
|
|
* devices (see nsh_usbconsole.c and usb_usbkeyboard for other versions
|
|
* for special USB console devices).
|
|
*
|
|
* Input Parameters:
|
|
* Standard task start-up arguments. These are not used. argc may be
|
|
* zero and argv may be NULL.
|
|
*
|
|
* Returned Values:
|
|
* This function does not normally return. exit() is usually called to
|
|
* terminate the NSH session. This function will return in the event of
|
|
* an error. In that case, a non-zero value is returned (EXIT_FAILURE=1).
