Hello,

Is there a way I can use debug_printf() inside C source (not C++). I've 
found <sys/strace.h> and <sys/ipctrace.h>.

Googling and I don't find information about what I need to include, and 
probably what I need to link.

#define TRACE
#include <stdio.h>
#include <sys/ipctrace.h>

int main(void)
{
   debug_printf("TEST\n");
}

It won't link, not finding _err_handler.

Thanks in advance.
Jason.
