1. Overview

   This is a module which provides a FIFO transport layer implementation
   for Management Interface.

2. FIFO command syntax

   The external commands issued via FIFO interface must follow the
   following syntax:
     * request = first_line argument*
     * first_line = ':'command_name':'reply_fifo'\n'
     * argument = (arg_name '::' (arg_value)? ) | (arg_value)
     * arg_name = not-quoted_string
     * arg_value = not-quoted_string | '"' string '"'
     * not-quoted_string = string - {',",\n,\r}

3. Dependencies

   3.1. Kamailio Modules
   3.2. External Libraries or Applications

3.1. Kamailio Modules

   The following modules must be loaded before this module:
     * No dependencies on other Kamailio modules.

3.2. External Libraries or Applications

   The following libraries or applications must be installed before
   running Kamailio with this module loaded:
     * none

4. Exported Parameters

   4.1. fifo_name (string)
   4.2. fifo_mode (integer)
   4.3. fifo_group (integer) fifo_group (string)
   4.4. fifo_user (integer) fifo_group (string)
   4.5. reply_dir (string)
   4.6. reply_indent (string)

4.1. fifo_name (string)

   The name of the FIFO file to be created for listening and reading
   external commands.

   Default value is NONE.

   Example 1.1. Set fifo_name parameter
...
modparam("mi_fifo", "fifo_name", "/tmp/openser_fifo")
...

4.2. fifo_mode (integer)

   Permission to be used for creating the listening FIFO file. It follows
   the UNIX conventions.

   Default value is 0660 (rw-rw----).

   Example 1.2. Set fifo_mode parameter
...
modparam("mi_fifo", "fifo_mode", 0600)
...

4.3. fifo_group (integer) fifo_group (string)

   Group to be used for creating the listening FIFO file.

   Default value is the inherited one.

   Example 1.3. Set fifo_group parameter
...
modparam("mi_fifo", "fifo_group", 0)
modparam("mi_fifo", "fifo_group", "root")
...

4.4. fifo_user (integer) fifo_group (string)

   User to be used for creating the listening FIFO file.

   Default value is the inherited one.

   Example 1.4. Set fifo_user parameter
...
modparam("mi_fifo", "fifo_user", 0)
modparam("mi_fifo", "fifo_user", "root")
...

4.5. reply_dir (string)

   Directory to be used for creating the reply FIFO files.

   Default value is “/tmp/”

   Example 1.5. Set reply_dir parameter
...
modparam("mi_fifo", "reply_dir", "/home/kamailio/tmp/")
...

4.6. reply_indent (string)

   Strings to be used for line indentation. As the MI data structure is
   tree oriendeted, the depth level will printed as indentation.

   Default value is “"\t" (TAB)”.

   Example 1.6. Set reply_indent parameter
...
modparam("mi_fifo", "reply_indent", "    ")
...

5. Exported Functions

   No function exported to be used from configuration file.

6. Example

   This is an example showing the FIFO format for the “get_statistics
   dialog: tm:” MI commad: response.

   Example 1.7. FIFO request
:get_statistics:reply_fifo\n
dialog:\n
tm:\n
\n
