Hi attached are two files that I am using to get one channel open. Now I need a second. I hate that I can not seem to remember enough C to do it.

Any assistence would be greatly appreciated.

I'm not sure I understand the question. You are opening a message queue as an IPC channel. What is stopping you from opening a second channel in the same way?

The second one always returns a negative number.

#include #include #include #include #include #include #include int ret; int main(void){ ret = msgget(....); if (ret < 0){ fprintf(stderr, "msgget failed: %s\n", strerror(errno)); exit(EXIT_FAILURE); } ret = msgget(.....); if (ret < 0){ fprintf(stderr, "msgget failed: %s\n", strerror(errno)); exit(EXIT_FAILURE); } return 0; } That is how you get a program to tell you what's wrong. With an error message from msgget, you should be able to figure out what is going wrong.
