ast_channel_dialed_causes_add()

int ast_channel_dialed_causes_add	(	const struct ast_channel *	chan,
		const struct ast_control_pvt_cause_code *	cause_code,
		int	datalen
	)

Add cause code information to the channel.

Since

11

This function makes use of datastore operations on the channel, so it is important to lock the channel before calling this function. The passed in data is copied and so is still owned by the caller.

Parameters

chan	The channel on which to add information
cause_code	The cause information to be added to the channel
datalen	The total length of the structure since its length is variable

Return values

0	on success
-1	on error

This function makes use of datastore operations on the channel, so it is important to lock the channel before calling this function.

Parameters

chan	The channel from which to retrieve information

Return values

Retrieve a ref-counted cause code information structure.

Since

11

This function makes use of datastore operations on the channel, so it is important to lock the channel before calling this function. This function increases the ref count of the returned object, so the calling function must decrease the reference count when it is finished with the object.

Parameters

chan	The channel from which to retrieve information

Return values

NULL	on search failure
Pointer	to a ref-counted ast_control_pvt_cause_code object containing the desired information

Set the topology of streams on a channel.

Parameters

chan	The channel to set the stream topology on
topology	The stream topology to set

Precondition

chan is locked

Note

If topology is NULL a new empty topology will be created and returned.

Return values

non-NULL	Success
NULL	failure
