static int action_add_agi_cmd	(	struct mansession *	s,
		const struct message *	m
	)			[static]

Add a new command to execute by the Async AGI application.

Parameters:

	s
	m	It will append the application to the specified channel's queue if the channel is not inside Async AGI application it will return an error

Return values:

	0	on success or incorrect use
	1	on failure to add the command ( most likely because the channel is not in Async AGI loop )

int ast_agi_register_multiple	(	struct ast_module *	mod,
		struct agi_command *	cmd,
		unsigned int	len
	)

Registers a group of AGI commands, provided as an array of struct agi_command entries.

Parameters:

	mod	Pointer to the module_info structure for the module that is registering the commands
	cmd	Pointer to the first entry in the array of command descriptors
	len	Length of the array (use the ARRAY_LEN macro to determine this easily)

Returns:

0 on success, -1 on failure

Note:

If any command fails to register, all commands previously registered during the operation will be unregistered. In other words, this function registers all the provided commands, or none of them.

/* This buffer sizes might cause truncation if the AGI command writes more data
   than AGI_BUF_SIZE as result. But let's be serious, is there an AGI command
   that writes a response larger than 1024 bytes?, I don't think so, most of
   them are just result=blah stuff. However probably if GET VARIABLE is called
   and the variable has large amount of data, that could be a problem. We could
   make this buffers dynamic, but let's leave that as a second step.

   AMI_BUF_SIZE is twice AGI_BUF_SIZE just for the sake of choosing a safe
   number. Some characters of AGI buf will be url encoded to be sent to manager
   clients.  An URL encoded character will take 3 bytes, but again, to cause
   truncation more than about 70% of the AGI buffer should be URL encoded for
   that to happen.  Not likely at all.

   On the other hand. I wonder if read() could eventually return less data than
   the amount already available in the pipe? If so, how to deal with that?
   So far, my tests on Linux have not had any problems.
