The code in question (line 34 of msg_bmk) is a preprocessor macro which is supposed to expand to a user stub for a new system call. Here is the line: _syscall2( int, msgbmk, int, msqid, int, MSG_TRIALS ) The file msg_bmk.h includes the header file <linux/unistd.h> which contains the macro definition. Any feedback would be great.
It's difficult to tell what the real problem is when looking at macros. You need to look at the code after macros have been expanded. Execute "gcc msg_client.c -E -dD -o msg_client.i" and take a look at what the _syscall2 macro generates. -- Michael Eager eager@xxxxxxxxxxxx 1960 Park Blvd., Palo Alto, CA 94306 650-325-8077
