Manual Pages  — GETBOOTFILE

NAME

getbootfile – get kernel boot file name

CONTENTS

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <paths.h>

const char *
getbootfile(void);

DESCRIPTION

The getbootfile() function retrieves the full pathname of the file from which the current kernel was loaded, and returns a static pointer to the name. A read/write interface to this information is available via the sysctl(3) MIB variable "kern.bootfile".

RETURN VALUES

If the call succeeds a string giving the pathname is returned. If it fails, a null pointer is returned and an error code is placed in the global location errno.

SEE ALSO

sysctl(3)

HISTORY

The getbootfile() function appeared in FreeBSD 2.0 .

BUGS

If the boot blocks have not been modified to pass this information into the kernel at boot time, the static string " /boot/kernel/kernel" is returned instead of the real boot file.
