INPUT_MT_INIT_SLOTS(9)                   Input Subsystem                   INPUT_MT_INIT_SLOTS(9)



NAME
       input_mt_init_slots - initialize MT input slots

SYNOPSIS
       int input_mt_init_slots(struct input_dev * dev, unsigned int num_slots,
                               unsigned int flags);

ARGUMENTS
       dev
           input device supporting MT events and finger tracking

       num_slots
           number of slots used by the device

       flags
           mt tasks to handle in core

DESCRIPTION
       This function allocates all necessary memory for MT slot handling in the input device,
       prepares the ABS_MT_SLOT and ABS_MT_TRACKING_ID events for use and sets up appropriate
       buffers. Depending on the flags set, it also performs pointer emulation and frame
       synchronization.

       May be called repeatedly. Returns -EINVAL if attempting to reinitialize with a different
       number of slots.
