Function fxaclient_ffi::fxa_ensure_capabilities

#[no_mangle]pub unsafe extern "C" fn fxa_ensure_capabilities(
    handle: u64, 
    capabilities_data: *const u8, 
    capabilities_len: i32, 
    error: &mut ExternError
)

Ensure that the device capabilities are registered with the server.

Safety

This function is unsafe because it will dereference capabilities_data and read capabilities_len bytes from it.
