I have a simple TCP multiprocess server...inside each child server(each of one handles distincted connection), I call a list of operation...suppose the following:
socket.async_read_some(....); //receive a client request socket.async_write_some(...); //respond to client request
socket.async_write_some(...); //independently of the client request, send something to the client
Have I use strand,or this situation doesn't cause problems? I don't use thread... thanks!!!
Without threads, you don't need a strand (the strand is implicit). But, even without threads, you still would need to make sure that the read or write operation is completed before issueing your next request. So, socket.async_read(...); // OK socket.async_write( ... ); // OK socket.async_read( ... ); // Potential error: 1st async_read may be still in progress Regards, Rutger
