std::os::raw::c_void - Rust
Description: API documentation for the Rust `c_void` enum in crate `std`.
Keywords: rust, rustlang, rust-lang, c_void

# Enum std::os::raw::c_void 1.1.0[−][src]

    #[repr(u8)]
    pub enum c_void {
        // some variants omitted
    }

Equivalent to C's `void` type when used as a pointer.

In essence, `*const c_void` is equivalent to C's `const void*` and `*mut c_void` is equivalent to C's `void*`. That said, this is not the same as C's `void` return type, which is Rust's `()` type.

Ideally, this type would be equivalent to `!`, but currently it may be more ideal to use `c_void` for FFI purposes.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
