Change the handling of non-fatal errors. Now the non-fatal error
messages are not shown in stderr and no assert() as default. The
behavior can be changed with LIBASOUND_DEBUG environment variable.
- added backward compatibility for older non-compatible functions
- added --with-compat-rc3 to configure script to build library
backwards compatible with 0.9.0rc3
- added symbol versioning like libc.so.6
- ALSA_0.9 - alsa base
- ALSA_0.9.0rc4 - first set of new functions (snd_pcm_hw_params_*)
- 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.
The configuration root (snd_config) can be specified for the internal routines.
The pcm_hooks code was recoded (independent code moved to control/setup.c).
Improved the pcm_multi plugin (added master configuration).
