⽤c语⾔编写界⾯,「分享」C语⾔如何编写图形界⾯
该楼层疑似违规已被系统折叠 隐藏此楼查看此楼
贴吧内经常有⼈问C语⾔是不是只能⽤于字符终端界⾯开发，不能⽤于图形界⾯。⼤家也都有回答，需要其他的库。MFC，GTK，QT。本⼈近期刚⽤GTK库加上纯C写成了第⼀个LINUX实⽤程序。现在与⼤家分享：

后台⽹络通迅模型接⼝声明client_socket.h
#ifndef CLIENT_SOCKET_Hdelta

void client_clo(int sockfd);
void client_nd(int sockfd,const unsigned char *buffer, const size_t count); size_t client_recv(int sockfd,unsigned char *buffer,size_t count);
#endif
