I hate to file a BZ on this, but I cannot find stropts.h. I have read in several places that it was removed from F9, but I cannot find any information about where the module macros (like I_PUSH, I_POP, etc..) were moved to.
Why do you need the I_PUSH/I_POP macros when Linux kernel doesn't support them? *** This bug has been marked as a duplicate of 439403 ***
If the kernel doesn't support them, then I have my answer. I am curious as to why they are not since the man pages are written in such a way that these macros appear to be mandated by the IEEE and Open Group. Also, I_PUSH is used in the GNU primer for initiating ptys. See the example here: http://www.gnu.org/software/libc/manual/html_node/Allocation.html#Allocation
