uint32_t DFlow_Init(_DFlow *df, 
                    void *AllBuffer, 
                    uint32_t TBufferLen,

);

Initialize the DFlow object and pass it various configuration parameters.

Parameters

• df：DFlow object。
• AllBuffer：All available memory areas are used to allocate buffers for Tx and Rx. Note: The memory area must be no smaller than TBufferLen * 2 + RBufferLen * 2.
• TBufferLen：The length of a single TxBuffer.
• RBufferLen：The length of a single RxBuffer.
• Func：The port function collection pointer, that is, an additional variable, binds a number of port functions and binds them uniformly to the DFlow object.

Return Value

• DFLOW_API_RETURN_DEFAULT(0x00)：Normal return.
• DFLOW_API_RETURN_ERR_PARAM(0x02)：Passing parameters does not meet the requirements; for example, some required port functions are not bind.
