Re: [Rd] Question on non-blocking socket

Hi Tomas, Apparently, inserting some kind of socketSelect() is essential when using non-blocking sockets and a client/erve architecture. That is at least one thing that I have learned ;-). In C++, between sending and requesting, I inserted a call to this function: bool wait(int s) { fd_set

[Rd] Question on non-blocking socket

non-blocking sockets in general. Is it allowed to execute a read and a receive command immediately after each other or must a short waiting loop be built in. I'm asking this because I'm running into the same problems in a C++ project as I did with RBaseX. Ben Engbers

Hi Tomas, I saw that the attached file is missing, I therefore have added it below. In the examples in your reply from 11/27/21 8:05 PM, you use the command 'socketSelect(list(con2))'. I have replaced my Sys.sleep() command with 'socketSelect(list(conn))'. Execution-time for all the tests has
