SSSocket, 意思是simple stupid socket interface
目的:
编写一个易于消息数据读写、非阻塞、跨平台的socket封装。目前用于手机网游客户端
优点:
1.采用非阻塞的连接和IO,即使是单线程也不会阻塞UI
2.提供读写buffer
3.对完整消息读取友好的API
缺点:
1.单线程使用方式,目前考虑是游戏的每一帧,非阻塞的读写一次数据。与多线程或者阻塞IO方式相比,读写速度上差了一些
2.buffer使用的只是原生数组。从缓冲区取出数据后,缓冲区尾部未读取数据会用内存拷贝的方式移动到头部
接口:
//create a socket , ready to connect to host define by host_name and port struct ssso* ssso_new(const char* host_name, int port); //close socket void ssso_free(struct ssso* so); //update socket, write data from buffer to socket, and if there is data readable, it return 1 int ssso_check(struct ssso* so); //peek whether has data of size in read buffer, return data or NULL void* ssso_peek(struct ssso* so, size_t size); //discard data of size in read buffer, mainly use after geting integrate message data using ssso_peek void ssso_discard(struct ssso* so, size_t size); //write data to buffer, after do ssso_check, the data may be send through socket void ssso_write(struct ssso* so, const void* data, size_t size); enum SSSO_STATUS ssso_status(struct ssso* so);
