ts_open_restricted3
Use a custom function for opening the touchscreen's input device file
Usage
#include <tslib.h> int (*ts_open_restricted)(const char *path, int flags, void *user_data);
Overview
ts_open_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_open_restricted pointer, it will be called by ts_open() instead of the open() system call directly.
It should open the input device at path with flags while user_data is currently unused.
Return value
the touchscreen input device' file descriptor
