    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 Fx 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.
