In the programming part of the bluetooth, normally are based on the two bluetooth stacks: Microsoft and Widcomm/Broadcom. Program created based on the Microsoft stack cannot be run on the Widcomm/Broadcom. In simple word, there isn't a single method which works on all stacks. Most notebook ...
Asocket APIis anapplication programming interface(API), usually provided by theoperating system, that allows application programs to control and use network sockets. Internet socket APIs are usually based on theBerkeley socketsstandard. In the Berkeley sockets standard, sockets are a form offile descr...

When a three-part address is specified, the last part is interpreted as a 16-bit quantity and placed in the right-most 2 bytes of the network address. This makes the three-part address format convenient for specifying Class B network addresses as "128.net.host''...
sin_port是端口号,16位长,网络字节序(network byte order);sin_addr是IP地址,32位长,网络字节序(network byte order)。sin_zero,8个字节,设置为0。 至于为何会使用两个数据结构sockaddr和sockaddr_in来表示地址,原因是如sa_family所指出的,socket设计之初本来就是准备支持多个地址协议的。不同的地址协议由自己不...

When the Internet took off in the 1990s with the World Wide Web, so did network programming. Web servers and browsers weren’t the only applications taking advantage of newly connected networks and using sockets. Client-server applications of all types and sizes came into widespread use. Today,...
