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
