The sock_send() function is used to send a message on a socket. It is similar to the send function in POSIX, but it also supports writing the data from multiple buffers in the manner of writev.

The function sends a message using the provided scatter/gather vectors. It retrieves the data from the buffers specified by the scatter/gather vectors and transmits it on the socket. The number of bytes transmitted is returned.

Notes

  • The sock_send() function sends a message on a socket using the provided scatter/gather vectors.
  • The function supports writing the data from multiple buffers.
  • The si_data parameter represents a list of scatter/gather vectors, where each vector contains a buffer and its length.
  • The si_data_len parameter specifies the length of the scatter/gather vector list.
  • The data to be sent is retrieved from the buffers specified by the scatter/gather vectors.
  • The number of bytes transmitted is stored in ret_data_len.
  • The specific behavior of the sock_send() function may vary depending on the runtime environment and underlying networking implementation.
