C - msgrcv adds characters to message received, very strange -

so msgrcv() function call works great, adds on characters received other process.

where sender process sends hello, receiver process receives hello@\n or hello\n@ or hello@,because prints different things randomly, hard cheat fix character pruning.

code:

    if (msgrcv(clientqueueid, &msg, sizeof(msg.data), 0, 0) == -1)     {         // no message received client     }     else     { ......... 

in case, printing msg.data shows has characters attached.

this how i'm printing:

printf("received message length %d: '%s'\n", (int)strlen(msg.data), msg.data); 

anyone have ideas why happening?

i knew strange issue...turns out it's problem client. had simple little function scanned '\n' , replaced '\0' "remove" new line wouldn't sent.

anyway, solution not remove new line client. somehow server reading correctly now, new line , all. hope helps down line.
