In Linux, the setsockopt function can be used to adjust the size of the buffer.<\/p>\n

The specific steps are as follows:<\/p>\n

    \n
  1. Include header files in the program.<\/li>\n
  2. Include two libraries: sys\/types.h and sys\/socket.h.<\/li>\n
  3. Create a socket and retrieve the socket file descriptor.<\/li>\n
  4. Set the buffer size using the setsockopt function.<\/li>\n
  5. Establish a socket file descriptor and set the receive buffer and send buffer size for it.<\/li>\n
  6. Note: SO_RCVBUF is used for setting the receive buffer size, while SO_SNDBUF is used for setting the send buffer size.<\/li>\n
  7. Check to see if the settings have been successfully configured.<\/li>\n
  8. Retrieve the receive buffer size and send buffer size for the specified socket by using the getsockopt function.<\/li>\n
  9. You can check if the buffer size has been successfully set by printing the values of rcvbuf and sndbuf.<\/li>\n<\/ol>\n

    It is important to note that the third parameter in the setsockopt function is used to specify the level of the option, for example SOL_SOCKET represents the socket level. In addition, the setting of buffer size may be limited by the system, so the specified size may not be fully met.<\/p>\n","protected":false},"excerpt":{"rendered":"
