WS_CHANNEL_STATE enumeration (webservices.h)

The different states that a channel can be in.

Syntax

typedef enum {
  WS_CHANNEL_STATE_CREATED = 0,
  WS_CHANNEL_STATE_OPENING = 1,
  WS_CHANNEL_STATE_ACCEPTING = 2,
  WS_CHANNEL_STATE_OPEN = 3,
  WS_CHANNEL_STATE_FAULTED = 4,
  WS_CHANNEL_STATE_CLOSING = 5,
  WS_CHANNEL_STATE_CLOSED = 6
} WS_CHANNEL_STATE;

Constants

WS_CHANNEL_STATE_CREATED Value: 0
WS_CHANNEL_STATE_OPENING Value: 1
WS_CHANNEL_STATE_ACCEPTING Value: 2
WS_CHANNEL_STATE_OPEN Value: 3
WS_CHANNEL_STATE_FAULTED Value: 4
WS_CHANNEL_STATE_CLOSING Value: 5
WS_CHANNEL_STATE_CLOSED Value: 6

Remarks

The following are the state transitions for a channel.

A channel may move to the WS_CHANNEL_STATE_FAULTED state even if WsAbortChannel was never called. This will only occur if the channel can no longer be used.

Note that only the valid state transitions are shown. Using a function not shown for a given state will result in an WS_E_INVALID_OPERATION error being returned from the function (or crash in the case of WsFreeChannel). For information on error codes, seeWindows Web Services Return Values.
