are in kvm_uread():
- the setting of errno before checking it in the lseek() was lost.
- EOF handling was lost. kvm_uread() retried forever on EOF. EOF is
not really an error, but report it one as in rev.1.2.
- reporting of errno after a read error was lost.
Fixed style bugs in rev.1.3 and rev.1.12.
Not fixed: errno is not reported after lseek() failures.
the statically compiled PS_STRINGS and USRSTACK variables. This prevents
programs using setproctitle from coredumping if the kernel VM is increased,
and stops libkvm users (w, ps, etc) from needing to be recompiled if only
the VM layout changes.
static executables that depend on this will need to be relinked (ie: do
this before 'ps'), but the dynamic linked stuff should be OK (ie: 'w')
Obtained from: NetBSD (not much point reinventing the wheel.. :-)
in all other places here.
This is a hack, the interface should be changed to use off_t's
everywhere around, but this will require to update all the programs
that happen to use libkvm.
