◆ ast_channel_dialed_causes_find_multiple()

struct ao2_iterator * ast_channel_dialed_causes_find_multiple ( const struct ast_channel *  chan,
const char *  chan_name 
)

Retrieve a ref-counted cause code information structure iterator.

Since
20.17.0, 22.8.0, 23.1.0

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
chanThe channel from which to retrieve information
chan_nameThe name of the channel about which to retrieve information
Return values
NULLon search failure
Pointerto a ao2_iterator object containing the desired information
