This is a realization of interprocess communication code, but it doesn't run out of the correct results (alternate shows ten times) is where there is a problem, please? Thank you bosses!

Pay attention to the coding standards

@ mouse_zhu bosses in the way you did, I although appear alternately, but the result or SERVER function infinite jumping out

CodePudding user response:

reference

but the result or SERVER function infinite out

What do you mean

CodePudding user response:

reference mouse_zhu reply: 3/f

but the result or SERVER function infinite jump out to

What do you mean

in the way you run on my computer, alternate displays infinite (server) received, but run on my classmate's computer have no problem, although I don't know why, but thank you!
