I picked msgsnd from the book Beginning Linux Programming (Wrox).
It has the following prototype:

int msgsnd(int msqid, const void* msg_ptr, size_t msg_sz, int msgflag);

and is called this way in an example C program in the book:

msgsnd(msgid, (void*)&some_data, MAX_TEXT, 0);

where some_data is the structure:

struct msg{
    long int msg_type;
    char text[MAX_TEXT];
};

Yes, I meant to cast it.
