buffersize

About this tag
The buffersize tag on WindowsForum.com covers discussions about buffer sizes in various computing contexts, including programming, system configuration, and hardware specifications. In programming, users explore why offsets like +1 or -1 are applied to buffers or casts, particularly in Windows driver development with structures like PFIRMWARE_REQUEST_BLOCK. System-level topics include modifying default socket buffer sizes (SO_SNDBUF, SO_RCVBUF) for all sockets via configuration changes. Hardware discussions reference buffer size as a specification for hard drives, such as 8 MB or 16 MB buffers in Western Digital drives. The tag brings together software and hardware perspectives on buffer size management.

    Windows 7 Modify the default value of socket buffer sizes

    In the socket programming, SO_SNDBUF and SO_RCVBUF will have the default value as the 8192 bytes when the size of RAM is greater than 19MB. Now, I want to change the socket buffer sizes for my sockets SO_SNDBUF, SO_RCVBUF. I know that one way is by setsockopt. But, I want to apply changes to...
