    Disable/Enable LAN card by C/C++

    Dear all,
    I had a problem when I made a kernel module in Linux by C++. The module is used to enable/disable network interfaces like ifup and ifdown commands. However I haven't yet found any system calls to support the function. I intended to call ifup/ifdown directly in the module. But, one more time, I could not know how to do that. Anyone here resolved this before, please let me know your ways. Thanks in advance.

    Have you tried to check ifconfig sources?

    use system command. or a better way would be to use the exec family.
