	I am having some trouble with the system call shmget(). When I tried
to get a segment of memory for sharing, the function was called as
shmid = shmget(IPC_PRIVATE,1024,0666). Shmid got a returned value of -1 and
the error was invalid argument. What have I done wrong?

	Since shared memory is a System V feature, do I have to set anything 
special in the normal cc command? I am using SunOS 4.0_Export on a SUN 3/50.
Any help would be appreciated.

	Thanks.
