|

* EVIOCGMASK - Retrieve current event mask
|
||||
*
|
||||
* This ioctl allows user to retrieve the current event mask for specific
|
||||
* 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.
|
||||
*
|
||||
* This ioctl may fail with ENODEV in case the file is revoked, EFAULT
|
||||
* if the receive-buffer points to invalid memory, or EINVAL if the kernel
|
||||
* does not implement the ioctl.

|

* EVIOCSMASK - Set event mask
|
||||
*
|
||||
* This ioctl is the counterpart to EVIOCGMASK. Instead of receiving the
|
||||
* current event mask, this changes the client's event mask for a specific
|
||||
* type. See EVIOCGMASK for a description of event-masks and the
|
||||
* argument-type.
|
||||
*
|
||||
* This ioctl provides full forward compatibility. If the passed event type
|
||||
* is unknown to the kernel, or if the number of event codes specified in
|
||||
* the mask is bigger than what is known to the kernel, the ioctl is still
|
||||
* accepted and applied. However, any unknown codes are left untouched and
|
||||
* stay cleared. That means, the kernel always filters unknown codes
|
||||
* regardless of what the client requests. If the new mask doesn't cover
|
||||
* all known event-codes, all remaining codes are automatically cleared and
|
||||
* thus filtered.
|
||||
*
|
||||
* This ioctl may fail with ENODEV in case the file is revoked. EFAULT is
|
||||
* returned if the receive-buffer points to invalid memory. EINVAL is returned
|
