rtems_shell_login_check_t | login_check | ||
) |
Initialise the shell creating tasks to login and run the shell sessions.
task_name | Name of the shell task. |
task_stacksize | The size of the stack. If 0 the default size is used. |
task_priority | The priority the shell runs at. |
forever | Repeat logins. |
wait | Caller should block until shell exits. |
login_check | User login check function, NULL disables login checks. |
int rtems_shell_libc_mounter | ( | const char * | driver, |

bool | wait, | ||
bool | echo | ||
) |
Run a shell script creating a shell tasks to execute the command under.
task_name | Name of the shell task. |
task_stacksize | The size of the stack. If 0 the default size is used. |
task_priority | The priority the shell runs at. |
input | The file of commands. Can be 'stdin' to use stdin. |
output | The output file to write commands to. Can be 'stdout', 'stderr' or '/dev/null'. |
output_append | Append the output to the file or truncate the file. Create if it does not exist. |
wait | Wait for the script to finish. |
