SPARSE_KEYMAP_SETUP(9)                   Input Subsystem                   SPARSE_KEYMAP_SETUP(9)



NAME
       sparse_keymap_setup - set up sparse keymap for an input device

SYNOPSIS
       int sparse_keymap_setup(struct input_dev * dev, const struct key_entry * keymap,
                               int (*setup) (struct input_dev *, struct key_entry *));

ARGUMENTS
       dev
           Input device

       keymap
           Keymap in form of array of key_entry structures ending with KE_END type entry

       setup
           Function that can be used to adjust keymap entries depending on device's deeds, may be
           NULL

DESCRIPTION
       The function calculates size and allocates copy of the original keymap after which sets up
       input device event bits appropriately. Before destroying input device allocated keymap
       should be freed with a call to sparse_keymap_free.
