this is my code
and Makefile
so seems that have no problem, but when i want compile it give me an error message that say
what should i do?
Code:
#include <sys/types.h>
#include <sys/param.h>
#include <sys/module.h>
#include <sys/sysent.h>
#include <sys/kernel.h>
#include <sys/systm.h>
static int
hello (struct proc *p, void *arg)
{
printf ("hello kernel.\n");
return 0;
}
static struct sysent hello_sysent = {
0,
hello
};
static int offset = NO_SYSCALL;
static int
load (struct module *module, int cmd, void *arg)
{
int error = 0;
switch (cmd){
case MOD_LOAD:
printf ("syscall loaded at %d\n", offset);
break;
case MOD_UNLOAD:
printf ("syscall unloaded from %d\n", offset);
break;
default:
error = EINVAL;
break;
}
return 0;
}
SYSCALL_MODULE (syscall, &offset, &hello_sysent, load, NULL);
and Makefile
Code:
SRCS= hello-1.c
KMOD= helloworld
.include <bsd.kmod.mk>
so seems that have no problem, but when i want compile it give me an error message that say
Code:
'AUE_NULL' undeclared here (not in a function)
what should i do?
