* Name: nsh_system
|
|
*
|
|
* Description:
|
|
* This is the NSH-specific implementation of the standard system()
|
|
* command.
|
|
*
|
|
* NOTE: This assumes that other NSH instances have previously ran and so
|
|
* common NSH logic is already initialized.
|
|
*
|
|
* Input Parameters:
|
|
* Standard task start-up arguments. Expects argc == 2 with argv[1] being
|
|
* the command to execute
|
|
*
|
|
* Returned Values:
|
|
* EXIT_SUCCESS or EXIT_FAILURE
|
|
*
