    SubjectCompatible fstat()
    Date
    From


    Hello,

    The Linux fstat() doesn't return any information number of blocks,
    or the byte-length of a physical hard disk.

    Device name : /dev/hda
    Device st_dev : 00000301
    Device st_rdev : 00000300
    Device st_size : 0
    Device st_blocks : 0
    Device st_blksize : 4096
    Device name : /dev/sda
    Device st_dev : 00000301
    Device st_rdev : 00000800
    Device st_size : 0
    Device st_blocks : 0
    Device st_blksize : 4096
    Device name : /dev/sdb
    Device st_dev : 00000301
    Device st_rdev : 00000810
    Device st_size : 0
    Device st_blocks : 0
    Device st_blksize : 4096
    Device name : /dev/sdc
    Device st_dev : 00000301
    Device st_rdev : 00000820
    Device st_size : 0
    Device st_blocks : 0
    Device st_blksize : 4096

    So, in a PORTABLE way, how do I find the block device with a
    certain size, perhaps even the largest or smallest? I need to
    have a customer plug in an external drive (USB) and be able
    to determine if it's big enough for a raw-data write (no
    file-system).

    Cheers,
    Dick Johnson
