//! Generates socket addresses on Unix platforms.

use std::path::PathBuf;
use std::process;

/// Returns a PathBuf for an app-specific Unix domain socket, optionally including a process ID for
/// apps that need separate sockets per-instance.
///
/// # Examples
///
/// App `foo` shares an instance of `thcon-listen` across all instances:
///
/// ```no_run
/// # use thcon::sockets::socket_addr;
/// # use std::path::PathBuf;
/// assert_eq!(
///     socket_addr("foo", false),
///     PathBuf::from("/tmp/thcon/foo.sock"),
/// )
/// ```
///
/// App `bar` requires a new instance of `thcon-listen` for each instance, since it can't share one:
///
/// ```no_run
/// # use thcon::sockets::socket_addr;
/// # use std::path::PathBuf;
/// let pid = std::process::id().to_string();
/// assert_eq!(
///     socket_addr("bar", true),
///     PathBuf::from(format!("/tmp/thcon/bar/{}.sock", pid)),
/// )
/// ```
