| | | | | | | | EV_RECEIPT is useful to disambiguating error conditions when multiple events structures are passed to kevent(2). The error code is returned in the data field and EV_ERROR is set. Approved by: rwatson (co-mentor)

* Our implementation of granpt(3) could be valid in the future.ed2009-08-241-15/+11
| | | | | | | | | | | | | | | | | | | | | When I wrote the pseudo-terminal driver for the MPSAFE TTY code, Robert Watson and I agreed the best way to implement this, would be to let posix_openpt() create a pseudo-terminal with proper permissions in place and let grantpt() and unlockpt() be no-ops. This isn't valid behaviour when looking at the spec. Because I thought it was an elegant solution, I filed a bug report at the Austin Group about this. In their last teleconference, they agreed on this subject. This means that future revisions of POSIX may allow grantpt() and unlockpt() to be no-ops if an open() on /dev/ptmx (if the implementation has such a device) and posix_openpt() already do the right thing. I'd rather put this in the manpage, because simply mentioning we don't comply to any standard makes it look worse than it is. Right now we don't, but at least we took care of it.

This removes the need for the shm_bsegsz member in struct shmid_kernel and should allow for complete support of SYSV SHM regions >= 2GB. - The shm_nattch member of struct shmid_ds is now an int instead of a short. - The shm_internal member of struct shmid_ds is now gone. The internal VM object pointer for SHM regions has been moved into struct shmid_kernel. - The existing __semctl(), msgctl(), and shmctl() system call entries are now marked COMPAT7 and new versions of those system calls which support the new ABI are now present. - The new system calls are assigned to the FBSD-1.1 version in libc. The FBSD-1.0 symbols in libc now refer to the old COMPAT7 system calls. - A simplistic framework for tagging system calls with compatibility symbol versions has been added to libc. Version tags are added to system calls by adding an appropriate __sym_compat() entry to src/lib/libc/incldue/compat.h.
