Add four new information flags SNDRV_SEQ_PORT_TYPE_HARDWARE, _SOFTWARE,
_SYNTHESIZER, _PORT for sequencer ports. This makes it easier for apps
like Rosegarden to make policy decisions based on the port type.
Remove several memory leaks by not aborting prematurely from a
snd_xxx_close() function when some operation fails.
This can happen when a USB device was unplugged.
snd_seq_port_info_get/set_timestamping()
snd_seq_port_info_get/set_timestamp_real()
snd_seq_port_info_get/set_timestamp_queue()
- increased the protocol version to 1.0.1.
the function itself still exists for compatibility
but protected by DOC_HIDDEN.
- a bit more comments about snd_seq_free_event.
- since alsa.m4 used snd_seq_create_event for checking libasound,
now it's replaced with snd_ctl_open.
- changed snd_config_get_id function to follow semantic of other get functions
- added snd_config_test_id
- added runtime pointer type (not persistent)
- added snd_config_make_pointer, snd_config_set_pointer, snd_config_get_pointer
- added type/contents checking for callback functions
- changed 'void *private_data' to 'snd_config_t *private_data'
- renamed card_strtype functions to card_driver
Control:
- fixed passing parameters to snd_ctl_async
Async handlers:
- added public snd_async_handler_get_signo function
Documentation:
- moved all documentation to source files
The sequencer API is totally recoded with the style of "encapsulation"
in other api.
The structure becomes opaque and accessed only via functions.
Other changes:
- There is no longer group in client and port info.
- snd_seq_query_subs_t is renamed to snd_seq_query_subscribe_t.
- snd_seq_delete_port takes only the port id argument instead of
port_info structure.
- snd_seq_input/output_buffer_size are renamed
as snd_seq_get_input/output_buffer_size.
Similarly snd_seq_resize_input/output_buffer are renamed as
snd_seq_set_input/output_buffer_size.
- snd_seq_get_named_queue is renamed to snd_seq_query_named_queue.
- Sync codes are removed temporarily from API.
- Subscription conditions are accessed via the corresponding functions.
convert_time is named now as time_update.
- snd_seq_get/set_queue_owner are removed.
Use snd_seq_get/set_queue_info instead.
- Instrument put/get/remove structure is unified as snd_instr_header_t.
- added pcm.front, pcm.rear, pcm.center_lfe blocks
* Added configuration for EMU10K1 (it's fully working one!!!)
* snd_config_redirect_load->snd_config_refer_load rename
* snd_config_search_alias code change (works also with pairs base.key)
* cleanups in the evaluate function (the function prototype has been changed)
The snd_config_expand functions expands the runtime contents (@func...).
Removed the environment variable replace code from the configuration parser.
Updated the alsa.conf configuration file.
They are half-automated output from the 0.5.x documents.
The sequencer API will be changed in near future
to suit with encapsulation implemented already in pcm api,
so do not trust the comments added here..
They are just for reference.
