GETBOOTFILE(3)		 BSD Library Functions Manual		GETBOOTFILE(3)

NAME
     getbootfile -- get	kernel boot file name

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 re-
     turned instead of the real	boot file.
