uinput: check for asprintf failure

2014-03-18T23:36:41+00:00

This doesn't really do much here, but strictly speaking: if asprintf returns
-1, devnode is undefined. So reset it to NULL to avoid weird pointers. And
also free the rest of the names if we ever have more than one device - which
also shouldn't happen.

Fix memory leaks when failing to create a uinput device

2014-02-27T03:22:50+00:00

For an invalid fd, or a failure to open the device, the pre-allocated uinput
device struct would leak.

We can drop the open_uinput() function now, since skipping to the error
handling means we'll return -errno anyway.

Revamp the API once again

2013-09-10T01:25:09+00:00

Another look at the current API showed some inconsistencies, rectified
in this commit:

libevdev_kernel_*: modify the underlying kernel device
libevdev_event_type_*: something with an event type
libevdev_event_code_*: something with an event code
libevdev_event_*: struct input_event-related functions (i.e. not device-related)
libevdev_property_*: something with a property
libevdev_*: anything applying to a device

Hopefully that's the last API change. Current symbols deprecated and aliased.

Warn if there are multiple devices with the same syspath

2013-09-03T07:01:42+00:00

Change to the previous code in that we continue looking at devices
even after we've found one. However, this way we can warn
the user when we can't guarantee syspath correctness.

uinput: don't try to set the syspath twice

2013-08-31T03:17:58+00:00

If we have it, stop searching for it. Otherwise a second device with the
same name would overwrite the first, causing a leak.

Add support for uinput device creation

2013-08-29T03:54:46+00:00

This lets libevdev provide a relatively generic interface for the
creation of uinput devices so we don't need to duplicate this across
multiple projects.

Most of this is lifted from the current test implementation, with a
couple of minor changes.

EV_REP needs special handling:
   Kernel allows to set the EV_REP bit, it doesn't set REP_* bits (which we
   wrap anyway) but it will also set the default values (500, 33).

Device node is guessed based on the sysfs path:
   The sysfs path contains a eventN file, that corresponds to our
   /dev/input/eventN number. Use it so clients can quickly get the device
   node, without a libudev dependency.
