    I have a Daemon and a kernel kext.
    in kext a buffer defined like :

    unsigned char* buffer;

    this buffer is dynamic.i mean buffer get characters from anywhere and in a certain time a daemon read buffer and write to file.
    now i want to pass a string in user mode to kext's buffer that this string write to file with other characters in buffer.

    How i can do that?

    Thanks
