xgnet oiocp(重叠完成端口) 封装库,网络引擎

oiocp:overlapped io completion port net_t use both overlapped and io completion port the put function [ void put(const void* buf,unsigned long lenInByte,int id); void put(netMsg_t *msg); void put(buf_t *first,buf_t *last); ] will make a copy of data that you passed in, net_t internal use mempool to keep the data that will send and have recved net_t will merge data(when send call not return and before next send call) and send in one call the data size that send in one call is limited(in sendTask_t) those async parameter of newServerMsg_t and newClientMsg_t [ unsigned long asyncRecv; unsigned long asyncSend; unsigned long asyncAccept; unsigned long asyncConnect; ] means overlapped operation count use one instance of net_t,you can create many peer listen to accept new connect and create many peer connect to any server include those listen peer in the same instance of net_t send those control msg(newServerMsg_t,newClientMsg_t,...) to SYS_ID to control the net_t net_t will send notify msg(newServerRetMsg_t,newClientRetMsg_tId,newConnectMsg_tId,...) to user with id = SYS_ID one instance of net_t can only work in one mode,stream mode or msg mode. stream mode: send use: void put(const void* buf,unsigned long lenInByte,int id); void put(netMsg_t *msg); recv use: buf_t *getBuf(bool wait); getBuf return a linked list,each buf_t may come from diffrent peer, the data and data size of buf_t have no relation from put call msg mode: send use: void put(const void* buf,unsigned long lenInByte,int id); void put(netMsg_t *msg); recv use: netMsg_t *get(bool wait); this function return a linked list, each netMsg_t may come from diffrent peer, the data and data size of netMsg_t is the same to each call of put //warning:see src for use with this two function netMsg_t &netMsg_t::operator>>(char *&v); netMsg_t &netMsg_t::operator>>(unsigned char *&v); warning:the byte order is in raw host order when use netMsg_t to serialize and deserialize data see netTutorial for use example.
