Function printwell_main 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn printwell_main(
    arg_count: c_int,
    arg_values: *const *const c_char,
) -> c_int

C entry point called from C++ main. Takes argument count/values and returns exit code.

Safety

• arg_values must be a valid pointer to an array of arg_count C strings
• Each C string in arg_values must be valid and null-terminated
