_SERCX2_CUSTOM_RECEIVE_TRANSACTION_CONFIG structure

Description

The SERCX2_CUSTOM_RECEIVE_TRANSACTION_CONFIG structure contains information that version 2 of the serial framework extension (SerCx2) uses to configure a new custom-receive-transaction object.

Members

`Size`

The size, in bytes, of this structure. The SerCx2CustomReceiveTransactionCreate method uses this member to determine which version of the structure the caller is using. The size of this structure might change in future versions of the Sercx.h header file.

`EvtSerCx2CustomReceiveTransactionInitialize`

A pointer to the driver-implemented EvtSerCx2CustomReceiveTransactionInitialize event callback function. This member is optional and can be set to NULL to indicate that the driver does not implement the function.

`EvtSerCx2CustomReceiveTransactionStart`

A pointer to the driver-implemented EvtSerCx2CustomReceiveTransactionStart event callback function. This member must point to a valid function.

`EvtSerCx2CustomReceiveTransactionCleanup`

A pointer to the driver-implemented EvtSerCx2CustomReceiveTransactionCleanup event callback function. This member is optional and can be set to NULL to indicate that the driver does not implement the function.

`EvtSerCx2CustomReceiveTransactionEnableNewDataNotification`

A pointer to the driver-implemented EvtSerCx2CustomReceiveTransactionEnableNewDataNotification event callback function. This member is optional and can be set to NULL to indicate that the driver does not implement the function.

`EvtSerCx2CustomReceiveTransactionQueryProgress`

A pointer to the driver-implemented EvtSerCx2CustomReceiveTransactionQueryProgress event callback function. This member must point to a valid function.

Remarks

The SerCx2CustomReceiveTransactionCreate method accepts a pointer to a SERCX2_CUSTOM_RECEIVE_TRANSACTION_CONFIG structure as an input parameter. Before calling SerCx2CustomReceiveTransactionInitialize, call the SERCX2_CUSTOM_RECEIVE_TRANSACTION_CONFIG_INIT function to initialize this structure.
