Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

sorry for the late fixup, the Ecore_Audio_Object is documented as "the
audio object" however, it is not, internally it is used as struct, thus
gdb gets confused.
This reverts commit 7a98f617e9.
this commit breaks compiling things against efl badly. i'm on holiday
and haver only a mini screen and keyboard wwith me so any serious wok
in hunting these issues isn't going to be fun or easy. as this causes
bad build brreaks this is worth a revert IMHO. please re-submit wwhen
you've tested against efl by building things against it. also our
public headers just should not have such ifdefs/if's that change api
presented based on how efl is cnfigured. we expose the same api and
macros and types regardless of internal config.
Summary:
Realization of audio data playback through WASAPI (Windows Audio Session API).(minimal)
WASAPI model:
1. Find a playback device (in the default system)
2. Register the client on the playback device.
3. Create a playback format for audio data.
4. Initialize the client with the created format, and access mode, ....
5. Take the object-rendering from the client for play the data stream.
6. Play data stream
ecore_audio model:
1. create a object for play the data stream(out object)
2. create a object to receive the data stream(in object)
3. register in the out-object the in-object
4. play data stream
Necessary:
Realize the ecore_audio object to play the data stream using the WASAPI model.
How implemented:
1. The object ecore_audio_out_wasapi is implemented
2. object ecore_audio_out_wasapi - the object constructor is find a playback device (in the default system)(WASAPI)
3. _ecore_audio_out_wasapi_ecore_audio_out_input_attach - register in the out-object the in-object
3.1 Register the client on the playback device.(WASAPI)
3.2 Create a playback format for audio data.(WASAPI)
3.3 Initialize the client with the created format, and access mode, ....(WASAPI)
4. _write_cb - play data
4.1 Take the object-rendering from the client for play the data stream.(WASAPI)
4.2 Play data stream(WASAPI)

Ecore_Audio.h had #ifdef HAVE_PULSE ... and that is just so wrong as
this is something an ap[p may or may not set in its config.h ... but
this certainly hase no place in our public headers. the api's there
should always be there... symbols always... just imtplementation may
be empty ... though ecore_audio doesnt build at all without pulse...
so it's moot.
so fix this build issue i found when fixing e build issues with meson
changes etc.
@fix
This covers ecore audio, avahi, buffer and con.
Summary: There are some typos and cacologigue statements in
doxygen of ecore_audio, ecore_avahi, ecore_buffer, and ecore_con.

CoreAudio support was initially introduced by commit
62e29b39f4 as an experimental feature.
It played basic sounds, but suffered from drawbacks: it was controlling
the master channel, and therefore any sound played by ecore_audio would
shut down a previous sound (e.g. background music) for the time of the
sound being played. So that wasn't exactly great... Also, after some
time, some hangs have been reported when playing a sound on input. Most
of the time, it translated as a pause in the main loop (see T3797).
More recently (several months ago), ecore_audio with CoreAudio stopped
working during 1.19 development...
So... CoreAudio support on macOS has never been great. And now it's fully
broken. Instead of trying to revive the thing, let just use PulseAudio.
PulseAudio can be installed without any trouble on macOS thanks to
package managers such as Homebrew. Actually, the efl package provided by
Homebrew already provides PulseAudio as a dependency. And it actually
just works very fine. Dropping CoreAudio seems therefore a nice option:
removes unmaintained code, fixes bugs, and add features.
Summary:
Ecore_Audio now supports Apple's CoreAudio to play sounds read by libsndfile.
edje_multisense integrates this new feature to enable PLAY_SAMPLE on OS X.
Test Plan:
Compiles, links and installs fine on OS X.
Run terminology and elementary_test to hear sound played on user input.

Also remove the Classes section from the Ecore_Audio_Group, we don't
need it as the pages are linked automatically

Very hackish implementation and probably not needed as libsndfile
virtual IO can be used instead, though it's a little more complicated
Signed-off-by: Daniel Willmann <d.willmann@samsung.com>
SVN revision: 80998
Allows reading from and writing to wav, ogg, etc. files. Support for
virtual IO as well to allow playing sounds from eet, which will be
needed in edje multisense.

This is still very much a work in progress, so expect some issues. The
signalling is using ecore events for now - that will change to callbacks
you can register callbacks for events on specific Ecore_Audio_Objects.
EO wasn't there when Ecore_Audio started, but it will probably move to
that in the future.
Otherwise have fun, don't break it (too much) and please send bug
reports and feedback to me.
