[so] Tema 2 Linux - mq_open

[Andrei Draga]

Am la un moment dat in gateway.c : 
        ...

        S = initializeazaS() ;
        C = mq_open ( "/gateway", O_CREAT | O_RDWR, 0777, &S ) ;
        printf("%d\n",C) ;
        printf("---%s\n", strerror(errno)) ;

        ...
Si cand rulez ./gateway obtin :
-1
---Invalid argument


De ce imi returneaza -1 de fiecare data mq_open ?
