* 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 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).
