//! WiFi connection detection module for LPU WiFi Manager
//!
//! This module handles:
//! - Cross-platform WiFi connection detection
//! - Linux detection using nmcli
//! - Windows detection using netsh

use std::process::Command;

/// Checks if the system is currently connected to LPU WiFi
///
/// # Returns
/// `true` if connected to an SSID starting with "LPU", `false` otherwise
///
/// # Platform Support
/// - Linux: Uses nmcli to check connection status
/// - Windows: Uses netsh to check connection status
///
/// # Examples
/// ```no_run
/// if llogin::wifi::check_lpu_wifi() {
///     println!("Connected to LPU WiFi");
/// } else {
///     println!("Not connected to LPU WiFi");
/// }
/// ```

/// Checks LPU WiFi connection on Linux systems using nmcli
///
/// # Implementation Details
/// - Uses nmcli command line tool
/// - Checks for active WiFi connections

///
/// # Returns
/// `true` if connected to LPU WiFi, `false` if not connected or on error
