* Adjust for kern.ps_strings and PS_STRINGS not being a pointer. ThisBruce Evans1998-12-161-17/+12
| | | | | | | | | | | | | fixes a type mismatch in the call to kvm_uread(). The bug has gone undetected for almost 3 years because kvm_uproc()'s protoype has been disabled for almost 4 years. Trust sysctlbyname() to work properly if it succeeds. Fixed style bugs in revs. 1.19 and 1.22. Notes: svn path=/head/; revision=41880
* Avoid the "Cannot allocate memory" problem that appears on heavilyDag-Erling Smørgrav1998-10-121-4/+10
| | | | | | | | | | | | loaded systems by retrying the sysctl() with a larger buffer if it fails with ENOMEM. For good measure, allocate 10% more memory than sysctl() claims is necessary. PR: 8275 Reviewed by: David Greenman <dg@freebsd.org> Notes: svn path=/head/; revision=40268
* Replace memory leaking instances of realloc with non-leaking reallocf.Warner Losh1998-09-161-1/+3
| | | | | | | | | | | | | | In some cases replace if (a == null) a = malloc(x); else a = realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is guaranteed to be the same thing. I've been running these on my system here w/o ill effects for some time. However, the CTM-express is at part 6 of 34 for the CAM changes, so I've not been able to do a build world with the CAM in the tree with these changes. Shouldn't impact anything, but...

* Allow /dev/null as path for the "/dev/mem" file, and assume that peoplePoul-Henning Kamp1998-06-301-20/+24
| | | | | | | | | | know what they're doing if they do that. This will allow ps to use the kvm_proc.c bits without having access to /dev/mem. Fix kvm_proc.c to not need /dev/mem for access to argv/envp Notes: svn path=/head/; revision=37316
* Fixed bugs in the conversion of kvm to to use procfs in rev.1.3. AllBruce Evans1998-01-161-9/+14
| | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=32568

* If the two recently added sysctl variables exist, use those rather thanPeter Wemm1996-02-241-2/+17
| | | | | | | | | | 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.

| | | | | | | | | | | 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. Notes: svn path=/head/; revision=7166
