message queue - System V MQ Text Length Issue -


i'm trying write simple chat app system v mqs having problem mtext value in struct.

struct join_buf {   long mtype;   char mtext[8]; };

when sent message struct inserted. written in server correct , wrong. see that; number of chars fullfilled 8.

what recommend me read mtext correctly ?

i think found mistake doing.

for (i = 0; < namelength; i++) {          joinbuf.mtext[i]=argv[1][i];     }     joinbuf.mtext[i]='\0';

without last line end of string length of char array. adding telling runtime it! not 1 bit more!
