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.
