Function xous::syscall::reply_and_receive_next_legacy

source · 
pub fn reply_and_receive_next_legacy(
    server: SID,
    msg: &mut Option<MessageEnvelope>,
    return_type: &mut usize
) -> Result<(), Error>
Expand description

Reply to the message, if one exists, and receive the next one. If no message exists, delegate the call to receive_syscall(). Allow specifying the scalar return type.

This is named _legacy because it is meant to work with calls that expect both Scalar1 and Scalar2 values, in addition to Scalar5.

§Arguments

  • server: The SID of the server to receive messages from
  • msg: An Option<MessageEnvelope> specifying the message to return.
  • return_type: If 1 or 2, responds to a BlockingScalarMessage with a Scalar1 or a Scalar2. Otherwise, will respond as normal.
