OBEXTRANSACTION (Windows Embedded CE 6.0)

1/6/2010

This structure contains the information for a specific transaction.

Syntax

typedef struct _obex_transaction {
  unsigned int uiConnectionId;
  unsigned int uiTransactionId;
  unsigned int uiOp;
  ObexCommand * pObex;
  MemAlloc ObexAlloc;
  MemFree ObexFree;
  ServerCallback ObexExecute;
} ObexTransaction;

Members

  • uiConnectionId
    The connection ID of the transaction (allocated by the server).
  • uiTransactionId
    The transaction ID (unique for a standard OBEX request-response exchange).
  • uiOp
    The operation selector. This member contains one of the following values.

    Value Description

    OBEX_REQ_REQUEST

    Place a request for service.

    OBEX_REQ_CLOSE

    The connection is closed.

    OBEX_REQ_INIT

    Initialize service.

    OBEX_REQ_UNLOAD

    The connection information is unloaded from the cache.

  • pObex
    Pointer to an OBEX server.
  • ObexAlloc
    Allocates the specified block of memory.
  • ObexFree
    Frees the specified block of memory.
  • ObexExecute
    Used to communicate the response from the command to the OBEX server.

Remarks

It is important to note that memory allocation function pointers will always be the same so it is legal to use ObexAlloc in one transaction to allocate block of memory and ObexFree from another transaction to free it (so memory allocated can be persistent across transactions).

To place an OBEX service request, uiOp must be equal to OBEX_REQ_REQUEST and pObex must not be equal to NULL.

Requirements

Header obexserver.h
Windows Embedded CE Windows CE .NET 4.0 and later
