Clarifiacation on header file "/usr/include/a.out.h"
 

Hi,

how does preprocessor "#include_next" work

$vi /usr/include/a.out.h

#ifdef _LIBC
# include_next <linux/a.out.h>
#else
# include <linux/a.out.h>
#endif
----------------------------------------------
"#include_next" ? how does this work ?

Thanks & Best Regards
