# Function std::io::stdout_locked

    pub fn stdout_locked() -> StdoutLock<'static>ⓘNotable traits for StdoutLock<'_>impl Write for StdoutLock<'_>

🔬 This is a nightly-only experimental API. (`stdio_locked` #86845)
Expand description

Constructs a new locked handle to the standard output of the current process.

Each handle returned is a guard granting locked access to a shared global buffer whose access is synchronized via a mutex. If you need more explicit control over locking, for example, in a multi-threaded program, use the `io::stdout` function to obtain an unlocked handle, along with the `Stdout::lock` method.

The lock is released when the returned guard goes out of scope. The returned guard also implements the `Write` trait for writing data.

### Note: Windows Portability Consideration

When operating in a console, the Windows implementation of this stream does not support non-UTF-8 byte sequences. Attempting to write bytes that are not valid UTF-8 will return an error.

# Examples

    #![feature(stdio_locked)]
    use std::io::{self, Write};

    fn main() -> io::Result<()> {
        let mut handle = io::stdout_locked();

        handle.write_all(b"hello world")?;

        Ok(())
    }
