NAME
       ts_error_fn - use a custom error function for libts library errors

SYNOPSIS
       #include <tslib.h>

       int (*ts_error_fn)(const char *fmt, va_list ap);



DESCRIPTION
       ts_error_fn() is by default implemented similar like this:

       static int errfn(const char *fmt, va_list ap)
       {
               return vfprintf(stderr, fmt, ap);
       }

       inside the library. It is exposed to the user and can be replaced by a
       custom error function. Simply assign your custom implementation to
       ts_error_fn like

       ts_error_fn = my_custom_errfn;

       It can be used to write the system log files, for example. The
       ts_print_mt test program has an example.
