Function win_kernel_driver::io_control_code

pub const fn io_control_code(
    device_type: u32, 
    function: u32, 
    method: Method, 
    access: Access
) -> u32

Creates an IOCTL code

Arguments

• device_type - The device type is a 32bit integer. It must match the kernel driver you're loading.
• function - The function code you want to send to the driver. Consult your driver's documentation for the available codes.DriverBuilder
• method - The IO method to use
• access - The access level (read/write/any) to use

Example

let device = 0x00000022; // FILE_DEVICE_UNKNOWN
let function = 0x800; // Some function code defined by the driver
 
// Generate an IO control code for a buffered read to the driver.
let ioctl = io_control_code(device, function, Method.BUFFERED, Access.READ);
