Function vmm_sys_util::ioctl::ioctl_with_ptr[−][src]

pub unsafe fn ioctl_with_ptr<F: AsRawFd, T>(
    fd: &F, 
    req: c_ulong, 
    arg: *const T
) -> c_int

Run an ioctl with a raw pointer.

Arguments

  • fd: an open file descriptor corresponding to the device on which to call the ioctl.
  • req: a device-dependent request code.
  • arg: a raw pointer passed to ioctl.

Safety

The caller should ensure to pass a valid file descriptor and have the return value checked.
