call

let call : (canister : Principal, name : Text, data : Blob) -> async (reply : Blob)

Calls canister's update or query function, name, with the binary contents of data as IC argument. Returns the response to the call, an IC reply or reject, as a Motoko future:

  • The message data of an IC reply determines the binary contents of reply.

  • The error code and textual message data of an IC reject determines the future’s Error value.

Note: call is an asynchronous function and can only be applied in an asynchronous context.
