In the shmget() man page it says:
SHMGET(2) UNIX Programmer's Manual SHMGET(2)
NAME
shmget - obtain a shared memory identifier
SYNOPSIS
#include <sys/types.h>
#include <sys/ipc.h>
#include <sys/shm.h>
int
shmget(key_t key, int size, int flag)
[....]
The mode of a newly created IPC object is determined by OR'ing the fol-
lowing constants into the flag parameter:
SHM_R Read access for user.
SHM_W Write access for user.
(SHM_R>>3) Read access for group.
[....]
But SHM_R and SHM_W are never defined in sys/shm.h or anywhere
else. Stevens APUE p. 467: uses SHM_R and SHM_W. Is this a bug in
the shmget(2) man page, are these missing from the header files?
I discovered that the defines existed under Solaris.
This doesn't seem very nice.. Can any one help me out on this one?
Thanks,
Cove
