# 1.0.0[−][src]Function std::env::args_os

    pub fn args_os() -> ArgsOs

Returns the arguments which this program was started with (normally passed via the command line).

The first element is traditionally the path of the executable, but it can be set to arbitrary text, and it may not even exist, so this property should not be relied upon for security purposes.

On glibc Linux systems, arguments are retrieved by placing a function in ".init_array". Glibc passes argc, argv, and envp to functions in ".init_array", as a non-standard extension. This allows `std::env::args` to work even in a `cdylib` or `staticlib`, as it does on macOS and Windows.

# Examples

    use std::env;

    // Prints each argument on a separate line
    for argument in env::args_os() {
        println!("{:?}", argument);
    }
