mixer: check for overflow and NULL return

In some old (2.6.32.x) kernel headers, asound.h does not include linux time.h
when __KERNEL__ is undefined, which may break userspace.
The build failures caused by this are similar to those fixed by c8333f8c.

tinycap: add capture time parameter
|
|
build: Redo Makefile a bit
|
|
fix some cppcheck warnings
|
|
A few changes:
* Don't hardcode 'gcc' and use $(CC) instead
* Split off CFLAGS/LDFLAGS so we can pick them up from the environment
* Add a static library build

mixer: remove separate info list
|
|
Each mixer_ctl has an associated snd_ctl_elem_info, which was
kept in a separate array with pointers from the mixer_ctl to
its corresponding snd_ctl_elem_info. This means double
pointer dereferences when looking up the info. It also means
extra work to add support for extending the arrays to include
dynamically added controls because the pointers from the ctl
array to the info array would have to be updated.
This patch removes the info list and gives each mixer_ctl struct
its own local snd_ctl_elem_info, removing the additional pointer
dereferencing.

initialize pcm_config to zero
|
|
sw_params ioctl() is failing with 'invalid parameter' error
since pointer to pcm_config passed from tinyplay is not zero
initialized, hence invalid values are passed for some
parameters.

tinypcminfo: make function pcm_get_format_name() static
|
|
When building tinyalsa with gcc 5.x, the following warnings appear:
tinypcminfo.c:97:52: warning: 'format_lookup' is static but used in inline function 'pcm_get_format_name' which is not static
return bit_index < ARRAY_SIZE(format_lookup) ? format_lookup[bit_index] : NULL;
^
tinypcminfo.c:97:35: warning: 'format_lookup' is static but used in inline function 'pcm_get_format_name' which is not static
return bit_index < ARRAY_SIZE(format_lookup) ? format_lookup[bit_index] : NULL;
And the build fails with:
tinypcminfo.o: In function `main':
tinypcminfo.c:(.text+0x2f0): undefined reference to `pcm_get_format_name'
collect2: error: ld returned 1 exit status
To fix this, this patch marks the pcm_get_format_name() as static,
since it's anyway only used in tinypcminfo.c.

Add a function to get an id of a control that can be
passed to mixer_get_ctl(). This can be used to lookup
a control by name and store its id for later use rather
than have the overhead of name lookup each time it is
used. Lookup by id is quick and avoids the disadvantage
that storing a pointer to the mixer_ctl object creates
a client with a dependency on the address of the internal
control array.

Revert "mixer: Control input value in mixer_ctl_set_value"
|
|
Allow setting of single byte control and make error from percent_to_int more consistent.
|

This reverts commit 0e07647e4b9c52bb5f3766f9564ed38b6030e556.
This commit disables reporting of an error when somebody requests an out
of range value from a control which seems like a bad goal to start with,
if something invalid is requested we should return an error not set
things to the nearest valid state.
Secondly since mixer_ctl_get_range_max returns an error for all control
types except TYPE_INTEGER, all controls that are not integers will be
set to -EINVAL with this patch included.

The users of tinyalsa had no way of knowing on which subdevice a stream had
been created. A new API, "unsigned int pcm_get_subdevice(struct *pcm)" returns
it. This information is filled during the pcm_open()

Tinyalsa pcm_wait() function does not wait on POLLIN events,
preventing it to be used when recording audio data.
This allows pcm_wait to wait on POLLIN events.

Currently, if a user sets a mixer with a percentage value
greater than the maximum, tinyalsa does not inform the user
about this "error" and silently replaces the user's value
by the maximum. However, if a user sets a mixer with an
integer value greater than the maximum, tinyalsa informs
the user with an error.
This patch purpose is to define the same behaviour in both
quoted cases: user is informed through an error.
