Enum CaOp 

pub enum CaOp {
    Read,
    Write,
}

Which CA operation failed — C’s read_action or write_action (rsrv/camessage.c).

C never lets the error KIND choose the status once a request has reached the database: read_action answers a negative dbChannel_get with ECA_GETFAIL (camessage.c:647-651) and write_action answers a negative dbChannel_put with ECA_PUTFAIL (camessage.c:781-789), throwing the dbStatus away in both. The same underlying failure therefore has two correct answers, one per direction, and a mapping that sees only the error cannot pick between them. Naming the direction at the call is what makes a read unable to reach a put status: no arm reachable under CaOp::Read yields ECA_PUTFAIL.

Variants

Read

C read_action — ca_get, ca_array_get_callback, a monitor update.

Write

C write_action / write_notify_action — ca_put, ca_put_callback.
