Hi
I'm not calling by myself, trying to enable standard debug output
In debug.h it is declared as:
[snip]
And in lwipopts.h I try to declare:
#define LWIP_PLATFORM_DIAG(m) {sprintf(buffer, m); \
SioWriteString(2, buffer); \
}
SioWriteString() is my function to write to my serialport.
LWIP_DEBUGF(debug,(("foo\n"))); This works (only format string)
LWIP_DEBUGF(debug,(("foo=%d\n", foo))); This don't works
I can't use printf becuse of library use system calls for _write()
In that case it is best to write your own alternative function to do it in
there, e.g.:
extern int my_printf(const char *fmt, ...);
#define LWIP_PLATFORM_DIAG(m) do {my_printf m;} while(0)
and elsewhere something like:
int my_printf(const char *fmt, ...)
{
int ret;
va_list ap;
va_start(ap, fmt);
ret = vsprintf(buffer, fmt, ap);
va_end(ap);
SioWriteString(2, buffer);
return ret;
}
