help:wrong behavior code:client-server IPC signal handling on POSIX Message Queue UNIX C programming
in a single main() function,so need signal handling. Use Posix Message Queue IPC mechanism , can ignore the priority and other linked list message,to implement the scenario:
client:Knock Knock
server:who's there
client: Eric
Server:Eric,Welcome.
client:exit
all process terminated
stdin->POSIX MsgQ client send "knock knock" to server->Server compares string and send "who's there" back to client
Below is my code,
What I got is :
client:knock knock
Server:Who's there?
client:eric
eric
client:Exit
Exit
1st round succeed get the right result.From 2nd round, the client put the same typing on console.
Please help. Remember to use gcc -lrt to link mq_function.
