void*(* alloc)(struct ast_channel *chan, void *params)

Definition at line 180 of file channel.h.

Referenced by ast_activate_generator(), and spandsp_fax_gateway_start().

void(* digit)(struct ast_channel *chan, char digit)

This gets called when DTMF_END frames are read from the channel

Definition at line 189 of file channel.h.

Referenced by __ast_read().

int(* generate)(struct ast_channel *chan, void *data, int len, int samples)

This function gets called with the channel unlocked, but is called in the context of the channel thread so we know the channel is not going to disappear. This callback is responsible for locking the channel as necessary.

Definition at line 187 of file channel.h.

Referenced by __ast_read(), ast_read_generator_actions(), cb_events(), and generator_force().

void(* release)(struct ast_channel *chan, void *data)

Channel is locked during this function callback.

Definition at line 182 of file channel.h.

Referenced by ast_activate_generator(), ast_deactivate_generator(), ast_hangup(), and internal_deactivate_generator().

void(* write_format_change)(struct ast_channel *chan, void *data)

This gets called when the write format on a channel is changed while generating. The channel is locked during this callback.

Definition at line 192 of file channel.h.
