-# This file describes the settings to be used by the documentation system
-# doxygen (www.doxygen.org) for a project.
-#
-# All text after a hash (#) is considered a comment and will be ignored.
-# The format is:
-# TAG = value [value, ...]
-# For lists items can also be appended using:
-# TAG += value [value, ...]
-# Values that contain spaces should be placed between quotes (" ").
-
-#---------------------------------------------------------------------------
-# Project related configuration options
-#---------------------------------------------------------------------------
-
-# This tag specifies the encoding used for all characters in the config file
-# that follow. The default is UTF-8 which is also the encoding used for all
-# text before the first occurrence of this tag. Doxygen uses libiconv (or the
-# iconv built into libc) for the transcoding. See
-# http://www.gnu.org/software/libiconv for the list of possible encodings.
-
-DOXYFILE_ENCODING = UTF-8
-
-# The PROJECT_NAME tag is a single word (or sequence of words) that should
-# identify the project. Note that if you do not use Doxywizard you need
-# to put quotes around the project name if it contains spaces.
-

-# The PROJECT_NUMBER tag can be used to enter a project or revision number.
-# This could be handy for archiving the generated documentation or
-# if some version control system is used.

-
PROJECT_BRIEF = "A wrapper library for evdev devices"

-
-# This tag can be used to specify a number of aliases that acts
-# as commands in the documentation. An alias has the form "name=value".
-# For example adding "sideeffect=\par Side Effects:\n" will allow you to
-# put the command \sideeffect (or @sideeffect) in the documentation, which

-# Doxygen selects the parser to use depending on the extension of the files it
-# parses. With this tag you can assign which parser to use for a given
-# extension. Doxygen has a built-in mapping, but you can override or extend it
-# using this tag. The format is ext=language, where ext is a file extension,
-# and language is one of the parsers supported by doxygen: IDL, Java,
-# Javascript, CSharp, C, C++, D, PHP, Objective-C, Python, Fortran, VHDL, C,
-# C++. For instance to make doxygen treat .inc files as Fortran files (default
-# is PHP), and .f files as C (default is Fortran), use: inc=Fortran f=C. Note
-# that for custom extensions you also need to set FILE_PATTERNS otherwise the
-# files are not read by doxygen.
-

-
-# If MARKDOWN_SUPPORT is enabled (the default) then doxygen pre-processes all
-# comments according to the Markdown format, which allows for more readable

-
-AUTOLINK_SUPPORT = YES
-
-# If you use STL classes (i.e. std::string, std::vector, etc.) but do not want
-# to include (a tag file for) the STL sources as input, then you should
-# set this tag to YES in order to let doxygen match functions declarations and
-# definitions whose arguments contain STL classes (e.g. func(std::string); v.s.
-# func(std::string) {}). This also makes the inheritance and collaboration

-
-SIP_SUPPORT = NO
-
-# For Microsoft's IDL there are propget and propput attributes to indicate

-# be useful for C code in case the coding convention dictates that all compound
-# types are typedef'ed and only the typedef is referenced, never the tag name.
-
-TYPEDEF_HIDES_STRUCT = NO
-
-# Similar to the SYMBOL_CACHE_SIZE the size of the symbol lookup cache can be
-# set using LOOKUP_CACHE_SIZE. This cache is used to resolve symbols given
-# their name and scope. Since this can be an expensive process and often the
-# same symbol appear multiple times in the code, doxygen keeps a cache of
-# pre-resolved symbols. If the cache is too small doxygen will become slower.
-# If the cache is too large, memory is wasted. The cache size is given by this

+ * event type. The argument must be of type "struct input_mask" and
+ * specifies the event type to query, the address of the receive buffer and
+ * the size of the receive buffer.
+ *
+ * The event mask is a per-client mask that specifies which events are
+ * forwarded to the client. Each event code is represented by a single bit
+ * in the event mask. If the bit is set, the event is passed to the client
+ * normally. Otherwise, the event is filtered and will never be queued on
+ * the client's receive buffer.
+ *
+ * Event masks do not affect global state of the input device. They only
+ * affect the file descriptor they are applied to.
+ *
+ * The default event mask for a client has all bits set, i.e. all events
+ * are forwarded to the client. If the kernel is queried for an unknown
+ * event type or if the receive buffer is larger than the number of
+ * event codes known to the kernel, the kernel returns all zeroes for those
+ * codes.
+ *
+ * At maximum, codes_size bytes are copied.

+ * ff_effects_max: This limits the maximum numbers of force-feedback effects.
+ * See below for a description of FF with uinput.
+ *
+ * This ioctl can be called multiple times and will overwrite previous values.
+ * If this ioctl fails with -EINVAL, it is recommended to use the old
+ * "uinput_user_dev" method via write() as a fallback, in case you run on an
+ * old kernel that does not support this ioctl.
+ *
+ * This ioctl may fail with -EINVAL if it is not supported or if you passed
+ * incorrect values, -ENOMEM if the kernel runs out of memory or -EFAULT if the
+ * passed uinput_setup object cannot be read/written.
+ * If this call fails, partial data may have already been applied to the

+ * UI_ABS_SETUP - Set absolute axis information for the device to setup
+ *
+ * This ioctl sets one absolute axis information for the input device to be
+ * created. It supersedes the old "struct uinput_user_dev" method, which wrote
+ * part of this data and the content of UI_DEV_SETUP via write().
+ *
+ * The ioctl takes a "struct uinput_abs_setup" object as argument. The fields
+ * of this object are as follows:
+ * code: The corresponding input code associated with this axis
+ * (ABS_X, ABS_Y, etc...)
+ * absinfo: See "struct input_absinfo" for a description of this field.
+ * This field is copied unchanged into the kernel for the
+ * specified axis. If the axis is not enabled via
+ * UI_SET_ABSBIT, this ioctl will enable it.
+ *
+ * This ioctl can be called multiple times and will overwrite previous values.
+ * If this ioctl fails with -EINVAL, it is recommended to use the old
+ * "uinput_user_dev" method via write() as a fallback, in case you run on an
+ * old kernel that does not support this ioctl.
+ *
+ * This ioctl may fail with -EINVAL if it is not supported or if you passed
+ * incorrect values, -ENOMEM if the kernel runs out of memory or -EFAULT if the
+ * passed uinput_setup object cannot be read/written.
+ * If this call fails, partial data may have already been applied to the
+ * internal device.

+ * log handler in libevdev_set_device_log_function(). Developers are encouraged

+ * more flexible when libevdev is used from within a shared library.
+ *
+ * If a caller sets both the global log handler and a per-context log
+ * handler, each device with a per-context log handler will only invoke that
+ * log handler.
+ *
+ * @note To set a context-specific log handler, a context is needed.
+ * Thus developers are discouraged from using libevdev_new_from_fd() as
+ * important messages from the device initialization process may get lost.
