Type Alias no_std_compat::os::raw::c_void
1.1.0 · source · pub type c_void = c_void;Expand description
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.
To model pointers to opaque types in FFI, until extern type is
stabilized, it is recommended to use a newtype wrapper around an empty
byte array. See the Nomicon for details.
One could use std::os::raw::c_void if they want to support old Rust
compiler down to 1.1.0. After Rust 1.30.0, it was re-exported by
this definition. For more information, please read RFC 2521.
