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.

RETURN VALUE

       user defined.
