Function casper_contract::ext_ffi::casper_update_associated_key [−][src]
pub unsafe extern "C" fn casper_update_associated_key(
account_hash_ptr: *const u8,
account_hash_size: usize,
weight: i32
) -> i32
This function attempts to update the given public key as an associated key
to the current account. Presently only 32-byte keys are supported; it is
up to the caller to ensure that the 32-bytes starting from offset
public_key represent the key they wish to add. Weights are internally
represented by a u8, this function will cause a Trap if the weight is
not between 0 and 255 inclusively. The result returned is a status code
for adding the key where 0 represents success, 1 means the key was not
associated to the account (to add a new key use add_associated_key), 2
means means permission denied (this could be because the function was
called outside of session code or because the key management threshold was
not met by the keys authorizing the deploy), and 3 means this key cannot
be changed to the specified weight because then it would be impossible to
meet either the deploy or key management thresholds (you may wish to try
again with a higher weight or after lowering the action thresholds).
Arguments
public_key- pointer to the bytes in wasm memory representing the public key to update, presently only 32-byte public keys are supportedweight- the weight to assign to this public key
