}Just include debug.h in your file.
- Requires C11 support (uses
_Generic). Consider using the flag-std=c11when compiling. - Literal chars have type
int, so you have to cast them tocharto print them as actual chars:
debug_raw("Find the", (char)'X'); // => Find the XFor quick debugging, include the header right where you need it:
void function(void) {
...
#include "debug.h"
debug(var); // => var = XXX
...
}To remove quickly all debugging output, define NDEBUG before the header inclusion:
#define NDEBUG
#include "debug.h"
...
debug(var); // Doesn't print anything
...
