Hi
I look up the <sane/sanei_debug.h>, and I also refer to the backends
wrote by others, but I still confused how to use DBG(level, fmt, ...) to
output specific information. e.g. I define below macro follow the
sanei_debug.h,
#include <sane/sanei_debug.h>
#define BACKEND_NAME MY_BACKEND
#define FUNCTION_DETAIL 1
#define FUNCTION_TRACE 2
I call DBG_INIT() in sane_init (). In some functions I use DBG(1, "%d",
param) and DBG(2, "%d", msg) to output debug information. But the backend
doesn't output any information that I wanted while I debug it . Does anyone
tell me what should I do to output these debug information?
Thank you.
