Prototype:
AiReturn FdxCmdTxUDPWriteIndexed (const AiUInt32 ul_Handle, const
TY_FDX_UDP_INDEXED_WRITE_IN *
px_UdpWriteIndexedIn,
TY_FDX_UDP_INDEXED_WRITE_OUT *
px_UdpWriteIndexedOut);
Driver Command:
FDX_TX_UDP_WRITE_INDEXED
Purpose:
This function is used to write a pure message to a defined queue of an UDP Sampling port
which has assotiated a input Queue. This message can be addressed by index
