| * Configuration of logging from VTY |
| * |
| * This module implements |
| * - functions that permit configuration of the libosmocore logging |
| * framework from VTY commands in the configure -> logging node. |
| * |
| * - functions that permit logging *to* a VTY session. Basically each |
| * VTY session gets its own log target, with configurable |
| * per-subsystem log levels. This is performed internally via the |
| * \ref log_target_create_vty function. |
| * |
| * You have to call \ref logging_vty_add_cmds from your application |
| * once to enable both of the above. |
