NetBSD pread(2) and pwrite(2). These still require indirection because
the arguments need to be converted to the correct types.
Delete svr4_sys_pread64() and svr4_sys_pwrite64(), since the arguments
for these calls do not need conversion, and the syscall switch calls
the native NetBSD system calls directly.
through SVR4 emulation layers to handle SVR4's pread64(2) and pwrite64(2),
since NetBSD's arguments are the same as the SVR4 64-bit system call
arguments.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code. i provided some help
getting swap and paging working, and other bug fixes/ideas. chuck
silvers <chuq@chuq.com> also provided some other fixes.
this is the rest of the MI portion changes.
this will be KNF'd shortly. :-)
- Fix memcntl()
- Fixed stat and mknod syscalls to properly disassemble and reassemble
dev_t values to/from emulation dev_t's
- Added pty (ptmx) subsystem at svr4net minor number 10 -- /dev/ptmx
- Implemented fork1() as fork() (should change if and when threads get
added to the system)
- fixed spellings in disclaimer in svr4_net.c; it looks like someone went
and did a s/nd/st/g on the whole file... yuck
- changed ptmx device to also halt on ENXIO (for pty files that exist with
no kernel pty to back them)
- fixed SVR4 setpgrp() to be a near equivalent to BSD setsid() (old
emulation didn't create a new session)
pread64(), pwrite(), pwrite64():
* The `offset' argument specifies an absolute offset within the file.
* After performing the read resp. write operation, restore the original
offset within the file.
Also, change the argument structure used by svr4_sys_prwite64() to
svr4_sys_pwrite64_args, instead of the 32-bit offset version.
