#include <tslib.h> void (*ts_close_restricted)(int fd, void *user_data);
ts_close_restricted() is useful if libts should not be run as root. If such a function is implemented by the user and assigned to the ts_close_restricted pointer, it will be called by ts_close() instead of the close() system call directly.
It should obviously close the device with file descriptor fd while user_data is currently unused.
