Expand description

Generates a wrapper function for a “bad” ioctl that reads and writes data to the kernel.

The arguments to this macro are:

  • The function name
  • The ioctl request code
  • The data type passed by this ioctl

The generated function has the following signature:

pub unsafe fn FUNCTION_NAME(fd: libc::c_int, data: *mut DATA_TYPE) -> Result<libc::c_int>
