NAME
    NameFromLock -- Returns the name of a locked object (V36)

SYNOPSIS
    success = NameFromLock(lock, buffer, len)
    D0                      D1     D2    D3

    BOOL NameFromLock(BPTR, STRPTR, LONG)

FUNCTION
    Returns a fully qualified path for the lock.  This routine is
    guaranteed not to write more than len characters into the buffer.  The
    name will be null-terminated.  NOTE: if the volume is not mounted,
    the system will request it (unless of course you set pr_WindowPtr to
    -1).  If the volume is not mounted or inserted, it will return an
    error.  If the lock passed in is NULL, "SYS:" will be returned. If
    the buffer is too short, an error will be returned, and IoErr() will
    return ERROR_LINE_TOO_LONG.

INPUTS
    lock   - Lock of object to be examined.
    buffer - Buffer to store name.
    len    - Length of buffer.

RESULT
    success - Success/failure indicator.

BUGS
    Should return the name of the boot volume instead of SYS: for a NULL
    lock.
