    v4l2object: Don't use mmap64 if off_t is 64-bit · 40262111
    Ting-Wei Lan authored
    The difference between mmap and mmap64 is the type of 'offset' argument.
    mmap64 always uses a 64-bit interger as offset, while mmap uses off_t,
    whose size can vary on different operating systems or architectures.
    
    However, not all operating systems support mmap64. Fortunately, although
    FreeBSD only has mmap, its off_t is always 64-bit regardless of
    architectures, so we can simply use mmap when sizeof(off_t) == 8.
