Function register 

pub fn register<T: Config>(
    para_id: ParaId,
    genesis_head: Vec<u8>,
    code_len: u32,
    code_hash: H256,
)

Ask the relay chain to register head data and validation code for a reserved para id.

The validation code itself stays here: only code_hash and code_len are sent. The caller uploads the blob to the relay chain separately, which accepts it only if it hashes to code_hash and is exactly code_len bytes long.

Costs

Takes Config::RegistrationConsideration for the head data and the declared code length, on top of the para id reservation. It is returned if the relay chain rejects the registration or if the caller later abandons it.

Warning: Doc-Only

This function is an automatically generated, and is doc-only, uncallable stub. See the real version in Pallet::register.
