Function USBAX172SendBuffer

USBAX172SendBuffer sends out an Ethernet frame:

int USBAX172SendFrame(int          DeviceIndex, 
                      void       * Buffer, 
                      const void * Data 
                      UINT         Len);

Parameters

DeviceIndex

Zero-based index of the AX172 interface.

Buffer

Pointer to the network stack's buffer control structure.

Data

Pointer to the data to send.

Len

Number of bytes to send.

return value

RTU_SUCCESS or a negative error code on failure.

The function sends asynchronously. When it returns, it is not guaranteed that the data has been sent. Once it has been sent, the driver will call system driver function RTUSYSEthernetFrameBufferSendDone.
