void osmo_tdef_vty_groups_init | ( | unsigned int | parent_cfg_node,
|  | struct osmo_tdef_group * | groups
| ) |  |

Convenience implementation for keeping a fixed set of timer groups in a program.

Install a 'timer [(group|names|...)] [TNNN] [(<val>|default)]' command under the given parent_node, and install a 'show timer...' command on VIEW_NODE and ENABLE_NODE. For a usage example, see tdef_test_config_root::c. The given timer definitions group is stored in a global pointer, so this can be done only once per main() scope. It would also be possible to have distinct timer groups on separate VTY subnodes, with a "manual" implementation, but not with this API.

Parameters

  [in] | parent_cfg_node | VTY node at which to add the timer configuration commands, e.g. CONFIG_NODE.
  [in] | groups | Global timer groups definition.

| ) |  |

Apply a timer configuration from VTY argument strings.

Employ both osmo_tdef_vty_parse_T_arg() and osmo_tdef_vty_parse_val_arg() to configure a T timer in an array of tdefs. Evaluate two arguments, a "T1234" argument and a "(0-2147483647|default)" argument, as from OSMO_TDEF_VTY_ARGS.

  [in] | tdefs | Array of timer definitions to look up T timer.
  [in] | args | Array of string arguments like { "T1234", "23" }.

Output one or all timers to the VTY, as for a VTY command like 'show timer [TNNNN]'.

If T_arg is NULL, print all timers in tdefs to the VTY. If T_arg is not NULL, employ osmo_tdef_vty_parse_T_arg() to select one timer from tdefs and print only that to the VTY.
