  • 아티클

1/6/2010

This function creates a connection request but returns information only after the connection has been established or has failed.

Syntax

HRESULT WINAPI ConnMgrEstablishConnectionSync(
  CONNMGR_CONNECTIONINFO *pConnInfo,
  HANDLE                 *phConnection,
  DWORD                   dwTimeout,
  DWORD                  *pdwStatus
);

Parameters

  • pConnInfo
    [in] Pointer to a CONNMGR_CONNECTIONINFO structure that contains the parameters that describe the requested connection.
  • phConnection
    [out] Pointer to the returned connection handle.
  • dwTimeout
    [in] Specifies a timeout, in milliseconds, for connection establishment.
  • pdwStatus
    [out] Pointer to the final status value. Can be one of the Connection Manager status constants. This parameter is only set if the pointer passed in is a non-null pointer. For details, see Connection Manager Status Constants.

Return Values

Returns S_OK if successful. Returns an error code if the function call failed or if a timeout has occurred.

Remarks

This function uses ConnMgrEstablishConnection and ConnMgrConnectionStatus internally to attempt to fully establish a connection before returning to the caller. The ConnMgrEstablishConnectionSync function does not provide an internal message pump. Therefore, the message queues of any user interface threads that call into this function are blocked until the function returns. A call to this function does not return until a connection has either been established or the attempt to create a connection has failed.

An application can only have one outstanding connection request at a time. Therefore, once ConnMgrEstablishConnectionSync or ConnMgrEstabishConnection is called, they cannot be called again to create another connection request until the first connection request is released with ConnMgrReleaseConnection.

Requirements

Header connmgr.h
Library cellcore.lib
Windows Embedded CE Windows CE .NET 4.2 and later
