Go language Development securities real-time quotes transcoding interface (multiple pits)

This is a creation in Article, where the information may have evolved or changed.

A friend gave a C + + real-time market interface, in which the actual volume of the structure of the deal is as follows:

1typedefstructTagstockreport2     {3WORD wdatasize;//Data Length4WORD wchecked;//Data Validation5 6         CharSzcode[stockcodesize];//stock code, ending with ' /'7         CharSzname[stocknamesize];//stock name, ending with ' /'8 9         intNtradingunit;//Trading Units (number of shares per lot)Ten  One         LongLtime;//UCT A  -         floatFlastclose;//prev. closed -         floatFOpen;//Open Today the         floatFHigh;//Highest -         floatFLow;//Minimum -         floatFnewprice;//Latest -         floatFvolume;//Volume +         floatFamount;//turnover -  +         floatFbuyprice[buysellcount];//Bid A         floatFbuyvolume[buysellcount];//The amount of the purchase, at         floatFsellprice[buysellcount];//Bid -         floatFsellvolume[buysellcount];//Sales Volume -}tstockreport, *pstockreport;

I converted it into the corresponding structure of go, and received the push over the market through the socket.

A few questions: 1, the C language structure of the field alignment rules seem to be different from the go language, some time to go to accept the time, add an empty placeholder field. 2, if a structure, in addition to the shape, floating point, there are some character types. There is no way to assign a single mapping to all the fields of a struct. So I have to take the data slice of the socket is assembled into the structure, you boss, for this hybrid structure, there is no good unified analysis of the socket data flow, the method of assignment.

On the code:
