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

◆ ast_channel_dialed_causes_channels()

struct ast_str * ast_channel_dialed_causes_channels ( const struct ast_channel * chan )

Retrieve a comma-separated list of channels for which dialed cause information is available.

Since: 11

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

NULL	on allocation failure
Pointer	to an ast_str object containing the desired information which must be freed

◆ ast_channel_dialed_causes_find()

struct ast_control_pvt_cause_code * ast_channel_dialed_causes_find	(	const struct ast_channel *	chan,

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
chan_name	The name of the channel about 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
